  258.      Any occurence of proceed(..) within the body of around advice is treated as the 

  259.      special proceed form (even if the aspect defines a method named proceed) unless

  261.      call.

  262.      </li>

  272.      AspectJ 1.2.1 correctly detects an attempt to access instance variables of the

  289.      </li>

  290.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=61768">61768</a> 

  291.      Static inner types of an aspect can now be referenced within the body of inter-type

  292.      declared methods in that aspect.

  293.      </li>

  294.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=62642">62642</a>

  303.      The Object[] given in response to a getArgs() call on a JoinPoint object is now

  304.      a value copy. 

  305.      </li>

  306.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=68991">68991</a>

  308.      </li>

  309.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=69459">69459</a>

  310.      A static inter-type method declaration is not allowed to hide an instance method. 

  311.      </li>

  312.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=70794">70794</a>

  313.      An inter-type declaration of an abstract method on a target type which is an interface

  314.      must be declared as public. 

  315.      </li>

  316.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=71372">71372</a>

  317.      Calls can be made to private static methods of enclosing types from the body of

  319.      </li>

  320.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=71377">71377</a>

  322.      private fields within the body of around advice. 

  323.      </li>

  324.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=71723">71723</a>

  325.      A non-privileged inter-type declared method cannot call protected methods defined in 

  326.      parent classes of the target type.

  327.      </li>

  328.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=74238">74238</a>

  329.      Any privileged calls made by the AspectJ runtime library are now correctly 

  330.      wrapped in doPrivileged blocks, with fall-back implementations, allowing

  331.      usage in restricted environments. 

  332.      </li>

  333.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=74245">74245</a>

  334.      Specifying the -proceedOnError flag will now cause the compiler to attempt

  336.      </li>

  337.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=76030">76030</a>

  338.      Runtime optimisations for cflow (in the case where there are no arguments bound in

  339.      the cflow pointcut) have been implemented. This can dramatically speed-up some programs

  340.      making heavy use of cflow. Thanks to the abc compiler team for detecting this performance

  341.      related bug and for piloting the fix. 

  342.      </li>

  343.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=54421">54421</a>

  351.      The 1.2.1 compiler supports an additional option, -showWeaveInfo, which will

  352.      produce informational messages concerning the activity of the weaver. For example:

  353.      </br>

  354.      <pre>

  355.      	Type 'tjp.Demo' (Demo.java:30) advised by around advice from 'tjp.GetInfo' 

  356.         (GetInfo.java:26) [RuntimeTest=true] 

  357.      </pre>

  358.      </li>

  359.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=44191">44191</a> 

  360.      AspectJ 1.2.1 improves the error messages issued in many of the infamous "can't find type"

  361.      scenarios. 

  362.      </li>

  363.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=46298">46298</a>

  364.      	The code generated by ajc is now more easily digested by many decompilers (but you

  365.      	wouldn't want to do that anyway would you?? ;) ). 

  366.      </li>

  367.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=49743">49743</a>

  368.      Performance optimisations in the AspectJ runtime library when using getSignature() and

  369.      toString(). 

  370.      </li>

  371.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=61374">61374</a>

  372.      AspectJ now includes its own version of BCEL under the org.aspectj namespace which eliminates

  373.      unwanted conflicts with BCEL versions inside JDKs or on classpaths in general.

  379.      The AspectJ 1.2.1 compiler includes the ability to dump information about the current state of the

  380.      compiler on failure. By default this only happens on an abort, but it can also be forced to

  381.      dump on error by specifying the property: org.aspectj.weaver.Dump.condition=error

  383.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=37020">37020</a>

  384.      The line number locations for method execution and static initialization join points now give

  385.      the first line of the method declaration (rather than the line number of the first line of code in

  386.      the method body) when the source code is compiled by ajc. 

  387.      </li>

  388.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=73369">73369</a>

  389.      A new jar, aspectjweaver.jar is included in the lib directory, which contains the subset

  390.      of aspectjtools.jar needed for weaving. The "aj" script is also moved into the bin directory.

  409.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=54819">54819</a> 

  410.      Error and warning messages coming from the weaving phase of compilation now

  411.      show source context wherever it is available, and also indicate as the source

  412.      location of the error either the class file or jar file from which the binary

  413.      source unit came.

  415.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=36430">36430</a>

  416.      A new -Xreweavable option has been added which allows class files to be woven

  417.      more than once.

  446.      New option -XlazyTjp defers creation of JoinPoint objects until just before

  447.      calling the advice body that requires them. This allows the cost of creating

  448.      JoinPoint objects to be avoided using an if() pointcut test that returns

  449.      false when the advice body is not required to be executed. Speed-ups of 10-100X are

  450.      obtained via this optimisation (as compared to putting the test inside the advice

  451.      body). 

  452.      </li>

  453.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=45441">45441</a>

  457.      Incremental compilation did not support the -outjar option, but silently

  458.      failed if it was specified. AspectJ 1.2 always performs a full build when

  459.      the -outjar option is present. 

  460.      </li>

  461.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=54965">54965</a>

  462.      Incremental compilation under AspectJ 1.2 is approximately twice as fast as

  463.      under AspectJ 1.1.1. 

  464.      </li>

  465.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=55134">55134</a>

  466.      Incremental compilation now deletes any additional class files generated during

  467.      the weave phase when the class file from whence they came is deleted. 

  468.      </li>

  469.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=54621">54621</a>

  470.      Incremental compilation will now detect changes (add, delete, modify) to class

  471.      files in directories on the inpath and will include them in incremental compilation.

  472.      </li>

  473.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=54621">54621</a>

  474.      Incremental compilation will now detect changes to jars on the inpath (and injars),

  475.      and trigger a full build if a jar is modified.

  476.      </li>

  477.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=54622">54622</a>

  478.      Incremental compilation will now detect changes to resources on the inpath.

  480.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=54618">54618</a>

  481.      Incremental compilation will now detect changes to any of the paths affecting

  482.      compilation, and triggers a full build if there has been any change since the

  483.      last build.

  484.      </li>

  485.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=50200">50200</a>

  488.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=49457">49457</a>

  489.      No error given when overloading pointcuts, unless variables are bound.

  491.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=50776">50776</a> 

  492.      Compilation failure when overriding an inter-type declared method with a

  495.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=51919">51919</a> 

  496.      Polymorphic inter-type declaration fails.

  501.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=41125">41125</a>

  502.      Variable names in the local variable table (for debugging) are now correctly

  503.      preserved in all cases. 

  504.      </li>

  505.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=43792">43792</a>

  506.      Improved support for non-US locales (and significantly boosted weaver 

  507.      performance at the same time). 

  508.      </li>

  509.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=35636">35636</a>

  510.      AspectJ 1.2 behaves much more gracefully when running out of memory. (It also

  511.      requires less memory than 1.1.1 did in any case).

  561.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=40943">40943</a> 

  562.      The ajc compiler now copies resource files from jars specified using the 

  563.      -injars option. When compiling with source directories, resources are <i>not</i>

  564.      copied - mirroring the behaviour of javac so as to cause minimum disruption

  565.      when switching between ajc and javac. 

  566.      (To copy resources from source directories, use the iajc Ant task 

  567.       <tt>sourceRootCopyFilter</tt> option.)

  568.      Thanks to Matthew

  569.      Webster for contributing many of the patches for this enhancement.

  570.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=39626">39626</a> 

  571.      ajc was erroneously putting aspectjtools.jar in the classpath of a compilation. 

  572.      This caused problems when attempting to compile projects using different versions

  573.      of any of the classes in aspectjtools.jar. Thanks to George Harley and Igor

  574.      Hjelmstrom Vinhas Ribeiro for their assistance in tracking this down.

  575.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=40257">40257</a>

  576.      Relative paths are now supported in ".lst" files.

  577.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=40771">40771</a> 

  578.      The Ajde apis are no longer coupled to swing. This is of most significance to AJDT

  579.      users on the Mac OS X platform, enabling AJDT to be used with Mac OS X.

  580.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=41254">41254</a> 

  581.      Of interest to those writing tools that need to interact with the structure model for 

  582.      AspectJ programs: the interface to the AspectJ structure model was significantly revised

  583.      and enhanced in 1.1.1.

  584.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=39462">39462</a>

  585.      A compiler exception was thrown when an abstract aspect in a library was extended by 

  586.      a concrete aspect using cflow. Thanks to Takao Naguchi for an easy to reproduce bug report.

  587.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=39479">39479</a> 

  588.      Compiler crashes when a constructor delegates to another constructor that uses a switch statement.

  589.      Thanks to Andy Clement for both the easy to reproduce bug report and the patch.

  590.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=41175">41175</a>

  591.      Declared exceptions were being lost on inter-type declarations made from binary

  592.      aspects in an aspect library.

  593.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=41359">41359</a>

  594.      Aspect per-clauses were not inherited by sub-aspects when using binary aspect libraries. 

  595.      Thanks to Chris Bozic for the easy to reproduce bug report.

  596.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=42539">42539</a>

  597.      The "+" pattern was being ignored for type patterns used in throws clauses. Thanks to 

  598.      Keith Sader for the easy to reproduce bug report.

  599.      <li><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=40807">40807</a>

  600.      If you specify no output directory, the iajc Ant task now defaults to using 

  601.      the source directory, following ajc and javac.

  602.      As a result, now you can use ajc to compile JSP's in Tomcat. 

  603.      Thanks to Ron Bodkin for investigating how to integrate ajc with Tomcat.

  666. <p>This release includes significant improvements to AspectJ Development 

  667. Environment (AJDE) support. The entire user interface has been revised and 

  668. streamlined. The AJDE features are more tightly integrated into JBuilder and 

  669. NetBeans/Forte support. JBuilder support now includes graphical configuration 

  670. file editing and an integrated AspectJ Browser tool. </p>

  679. <h3><a name="1.0.5compiler">Compiler</a></h3>

  680. 

  681. <p> This was another compiler release primarily concerned with fixing

  682. corner cases in the language implementation.  Our handling of nested

  683. classes, the assert statement, and cflow were the principal offenders

  684. this time.  Thanks to Nicholas Alex Leidenfrost and Patrick Chan for

  685. their clear and concise bug reports on some of these issues.  </p>

  689. <h4><span style="font-weight: 400">This release includes significant 

  690. improvements to AspectJ Development Environment (AJDE) support. All known bugs 

  691. have been fixed, and the core framework quality has been significantly increased 

  692. thanks to the adoption of a unit test suite.  The following changes apply 

  693. to all of the AJDE NetBeans/Forte, JBuilder, and the AspectJ Browser support.  

  694. NetBeans/Forte and JBuilder-specific changes are listed below.  </span></h4>

  695. 

  696. 

  697. <ul>

  698.   <li><span style="font-weight: 400">The entire user interface has been revised 

  699.   and streamlined.</span></li>

  700.   <li>The structure view and browser have a new UI, and offer both a file-based 

  701.   and global structure views.  All views expose node ordering, node 

  702.   filtering, and association filtering functionality.  The global views 

  703.   expose a package tree as well as the global inheritance and crosscutting 

  704.   structure.  </li>

  705.   <li>Structure view navigation now has a history exposed by back/forward.</li>

  706.   <li>The is a new build configuration management UI.</li>

  707.   <li>The compiler preferences UI now includes access to all build options.</li>

  708.   <li>Error messages have been improved, and the structure views include 

  709.   annotations of nodes with errors and warnings.</li>

  710. </ul>

  711. 

  712. <h4>AJDE for JBuilder</h4>

  713. 

  714. 

  715. <p>Integration into the JBuilder IDE is more streamlined.  In addition:</p>

  716. 

  717. 

  718. <ul>

  719.   <li>The AspectJ Browser is included as a tool that replaces JBuilder's 

  720.   "Project View" and can be used to navigate the global structure of your system 

  721.   (including the crosscutting and inheritance structure).</li>

  722.   <li>Inline structure annotations in the editor's gutter can now expose all of 

  723.   the structure presented in the structure view, and can be used to navigate in 

  724.   a similar way.  Note that there are preferences for toggling which of 

  725.   these appear.</li>

  726.   <li>Building is better integrated and the JBuilder build toolbar is removed 

  727.   when AJDE is enabled.</li>

  728.   <li>Build configurations can be selected from the build button's menu.</li>

  729.   <li>Execution is better integrated: instead of a separate "run" button 

  730.   JBuilder's run and debug can be used.  Note that for new projects you 

  731.   will need to use the "AspectJ Runtime" library, which will be added to your 

  732.   preferences automatically.</li>

  733.   <li>A new graphical build configuration editor can be used by double-clicking 

  734.   ".lst" files that have been added to the project. </li>

  735.   <li>Error messages now match JBuilder's look-and-feel and behavior.  

  736.   Seeking to column numbers now works in addition to line numbers.</li>

  737. </ul>

  738. 

  739. 

  740. <h4>AJDE for Forte/NetBeans</h4>

  741. 

  742. 

  743. <p>Integration into the NetBeans IDE is more streamlined.  In addition:</p>

  744. 

  745. 

  746. <ul>

  747.   <li>NetBeans 3.3.2 and SunONE Studio 4 are supported.</li>

  748.   <li>Multiple filesystems are supported.</li>

  749.   <li>Default project build configurations (all project files) are now 

  750.   supported.</li>

  751.   <li>Build configurations can be selected in the tool bar.</li>

  752.   <li>Regular NetBeans execution and debugging is supported.  Note that you 

  753.   have to add netbeans/lib/ext/aspectjrt.jar file to your project configuration.</li>

  754.   <li>Class files are generated beside source files (NetBeans/javac default).  

  755.   There is currently no way to specify a target directory.</li>

  756. </ul>

  757. 

  758. 

  759. <h4>AJBrowser</h4>

  760. 

  761. 

  762. <ul>

  763.   <li>The browser now supports main class execution.  Set the main class in 

  764.   the options dialog, and make sure that both the Java executable is on your 

  765.   path, and the class that you expect to execute on your classpath.</li>

  766.   <li>The error messages UI has been improved.</li>

  767. </ul>

  815.   handling for the wrong number number of arguments to

  816.   <code>proceed</code>.  This has been turned into a nice error

  817.   message.  A number of other bug reports related to around advice and

  818.   proceed have also been fixed, including the ability to change the

  819.   bindings for <code>this</code> and <code>target</code> using proceed

  820.   in around advice.

  821.   </li>

  822.   <li>David Walend gets the <em>black thumb</em> award for the most

  823.   bug reports submitted by a new user.  His bug report on the 

  824.   behavior of after returning advice led to some valuable clarifications

  825.   of this part of the language spec.

  826.   </li>

  827.   <li>A number of places where ajc didn't fully comply with the Java

  828.   Language Spec have been fixed in this release.  Thanks to Neal

  829.   Gafter for reporting many of these.

  830.   </li>

  831. </ul>

  832. 

  833. <h4>Incompatible changes</h4>

  834. 

  835. <p>Two potentially surprising incompatible changes have been made to

  836. ajc in order to bring the compiler into compliance with the 1.0

  837. language design.  These changes will be signalled by clear warning or

  838. error messages at compile-time and will not cause any run-time

  839. surprises.  We expect most users to never notice these changes.</p>

  840. 

  841. <ul>

  842.   <li>The obsolete class

  843.   <code>org.aspectj.lang.MultipleAspectsBoundException</code> has been

  844.   removed from aspectjrt.jar.  This class had not been used since

  845.   AspectJ-0.8 and should have been removed prior to the 1.0 release.

  846.   It is not documented as part of the 1.0 language spec.  This change

  847.   will cause a compile-time type not found error in any code that

  848.   refers to this exception.</code>

  849. 

  850.   <li>The compiler was not correctly implementing the AspectJ-1.0

  851.   language design for some uses of after returning advice.  This

  852.   compiler behavior was fixed, and advice whose behavior might be

  853.   changed by this bug fix will be highlighted with a compiler

  854.   warning.  More information about some of these changes can be found

  855.   in the <a href="porting.html#pre-1.0.4">porting notes</a>.</li>

  858. <h3><a name="1.0.4ajde">AJDE</a></h3>

  859. 

  860. 

  861. <p>This is the first release of AJDE support with significant external 

  862. contribution.  A big thanks goes out to Phil Sager for porting the AJDE for 

  863. Forte/NetBeans support to NetBeans 3.3.1 and improving the integration into 

  864. NetBeans.</p>

  911. 

  912. <h3><a name="1.0.4taskdefs">Ant tasks</a></h3>

  913. <ul>

  914.    <li>Repackaged to fit into the AspectJ product directory - e.g., 

  915.        <code>aspectj-ant.jar</code> moved to <code>lib</code> 

  916.        as expected by <code>examples/build.xml</code>.

  917.    </li>

  937. <h3><a name="1.0.3compiler">Compiler</a></h3>

  938. <p> This release fixes a single significant bug in 1.0.2 where ajc

  939. could generate unreachable code in <code>-usejavac</code> or

  940. <code>-preprocess</code> mode.  This would happen when around advice

  941. was placed on void methods whose body consisted solely of a

  942. <code>while (true) {}</code> loop.  We now properly handle the

  943. flow-analysis for this case and generate code that is acceptable to

  944. javac.  Thanks to Rich Price for reporting this bug.

  945. </p>

  946. 

  947. <h3><a name="1.0.3taskdefs">Ant taskdefs</a></h3>

  953. <h2><a name="1.0.2">1.0.2</a></h2>

  954. 

  955. <p> This release is mainly about keeping up with the Joneses.  To keep

  956. up with SUN's release candidate for J2SE1.4, we now officially support

  957. the new 1.4 assertions and running on the 1.4 VM.  In honor of the

  958. public review of JSR-45 Debugging Support for Other Languages we

  959. implement this spec for AspectJ.  We support Borland's recent release

  960. of JBuilder 6, and since some of our users are starting to work on Mac

  961. OSX, AJDE now works nicely on this platform.  We also fixed almost all of

  962. the bugs you reported in 1.0.1.

  971. <h3><a name="1.0.2compiler">Compiler</a></h3>

  972. 

  973. <ul>

  974.   <li>Official support for <code>-source 1.4</code> option to compile new

  975.       <a href="http://java.sun.com/j2se/1.4/docs/guide/lang/assert.html">1.4 assertions</a>.

  976.       This makes ajc completely compatible with j2se-1.4.

  977.   </li>

  978.   <li>Implementation of <a href="http://jcp.org/jsr/detail/45.jsp">

  979.       JSR-45 Debugging Support for Other Languages</a> so that debuggers which

  980.       correctly implement this specification will be able to accurately debug

  981.       any AspectJ program at a source code level.  We are not currently

  982.       aware of any debuggers that implement this so far, but expect that

  983.       as j2se-1.4 becomes widely available this will change.

  984.   </li>

  985.   <li>As proposed by Arno Schmidmeier and seconded by Nick Lesiecki, we now have an

  986.       experimental <code>-Xlint</code> option that will provide warnings when

  987.       type patterns used in pcds have no bindings.  We are very interested in

  988.       feedback on the usefulness and suggested improvements for this feature.

  989.   </li>

  990.   <li>Several significant bugs in the implementation of around advice have been fixed.

  991.       These include issues with <a href="http://aspectj.org/jitterbug/aspectj-bugs/resolved?id=632">

  992.       dynamic tests</a>, with

  993.       <a href="http://aspectj.org/jitterbug/aspectj-bugs/resolved?id=620">

  1000.       verified bugs in 1.0.1 have been fixed.  The two outstanding bugs

  1001.       have relatively easy work-arounds.  Thanks as usual to everyone who

  1002.       submitted a bug report.

  1003.   </li>

  1004.   <li>We no longer use the <code>SYNTHETIC</code> attribute to label declarations

  1005.       added by the aspectj compiler.  We were using this attribute in compliance

  1006.       with <a href="http://java.sun.com/docs/books/vmspec/2nd-edition/html/ClassFile.doc.html#80128">

  1007.       the JVM Specification</a>; however, we've found that many tools expect

  1008.       this attribute to only be used for the narrow purpose of implementing

  1009.       Java's inner classes and that using it for other synthetic members can confuse

  1010.       them.  This led to problems both

  1011.       <a href="http://aspectj.org/jitterbug/aspectj-bugs/resolved?id=649">with javap</a> and

  1012.       <a href="http://aspectj.org/jitterbug/aspectj-bugs/resolved?id=646">with javac</a>.

  1013.   </li>

  1072.     Please try using another JPDA-compliant debugger.  If it uses

  1073.     JDI correctly, then it should navigate to line numbers

  1090. 

  1091. <p> This release fixes a significant performance issue in the

  1092. compiler, reported by Rich Price, that could lead to extremely long

  1093. compiles in systems with many aspects and classes.  Several other

  1094. small bugs related to reporting compilation errors have also been

  1095. fixed, see <a

  1096. href=http://aspectj.org/jitterbug/aspectj-bugs/resolved?id=610>this

  1097. bug report</a> for an example.

  1098. </p>

  1099. 

  1100. <p> A new experimental flag has been added,

  1101. <code>-XaddSafePrefix</code>, that will cause the prefix

  1102. <code>aspectj$</code> to be inserted in front of all methods generated

  1103. by ajc.  This mode should be helpful when using aspectj with tools

  1104. that do reflection based on method names, such as EJB tools.  Thanks

  1105. to Vincent Massol for pointing out the importance of this.  It is

  1106. expected that this prefix will either become the default compiler

  1107. behavior in the future or a non-experimental flag will replace it.

  1229. 

  1230. <ul>

  1231.   <li>Thanks to Robin Green for suggesting that we could relax the

  1232.   rules for inheriting multiple concrete members in order to allow

  1233.   those unambiguous cases where one member has already overridden the

  1234.   other.  <a href=http://aspectj.org/pipermail/users/2001/001289.html>

  1235.   More details...</a></li>

  1236. 

  1237.   <li>Ron Bodkin encouraged us to examine the details of privileged

  1238.   aspects more closely.  This led to several small improvements and

  1239.   clarifications to this language feature.

  1242. </ul>

  1243. 

  1244. <h2><a name="1.0rc3compiler">Compiler</a></h2>

  1245. 

  1246. <p>This release saw several changes to the compiler in order to

  1247. work-around known bugs in different JVMs, or to otherwise mimic the

  1248. behavior of javac rather than necessarily following the Java Language

  1249. Specification.</p>

  1250. 

  1251. <ul>

  1252.   <li>Hanson Char reported a bug where ajc's correctly generated

  1253.   bytecodes for some references to interface fields result in verify

  1254.   errors on certain JVMs.  While this is a known bug in those JVMs,

  1255.   we've modified ajc to be bug compatible with all the other Java

  1256.   compilers out there to work-around this JVM bug.

  1257.   <a href=http://aspectj.org/jitterbug/aspectj-bugs/resolved?id=551>

  1258.   More details...</a></li>

  1259. 

  1260.   <li>Frank Hunleth discovered a similar bug where ajc's correct

  1261.   bytecodes could lead to essentially random method dispath due to a

  1262.   bad bug in the 1.3.0 JVM from Sun.  Even though this bug was fixed

  1263.   in the 1.3.1 and 1.2.2 JVMs, we have introduced the appropriate

  1264.   work-around in ajc's code generation. <a

  1265.   href=http://aspectj.org/jitterbug/aspectj-bugs/resolved?id=580>More

  1266.   details...</a></li>

  1267. 

  1268.   <li>Thomas Haug (as well as several other members of his group)

  1269.   reported a problem with name binding where ajc was behaving

  1270.   differently than javac.  This problem was resolved to come from a

  1271.   class created by an obfuscator that conflicted with his package

  1272.   names.  The JLS doesn't clearly specify which of these two behaviors

  1273.   is correct.  Nevertheless, ajc has been changed to treat packages

  1274.   more like javac does in order to minimize this sort of problem in

  1275.   the future.  <a

  1276.   href=http://aspectj.org/jitterbug/aspectj-bugs/resolved?id=574> More

  1277.   details...</a></li>

  1278. 

  1279.   <li>Several "real" bugs in ajc were also reported and fixed.  Toby

  1280.   Allsopp gets credit for reporting two of them.  The most interesting

  1281.   of these bugs to me was his report that we just didn't support

  1282.   qualified anonymous inner constructors.  This is a part of the Java

  1283.   language that ajc has never supported over its almost 3 year

  1284.   history.  We'd just noticed this ourselves when running the jacks

  1285.   compiler test suite from the jikes group, and had added the feature

  1286.   days before getting our first bug report for it not being

  1287.   there.</li>

  1290. <h2><a name="1.0rc3ajde">AJDE</a></h2>

  1293.   <li>The structure view has been improved.  </li>

  1294.   <li>Multiple user-configurable views are supported.</li>

  1295.   <li>Structure tree filtering and ordering has been added.  </li>

  1296.   <li>A split tree mode has been added to permit the navigation of multiple 

  1297.   views on the same structure.  </li>

  1298.   <li>The view can also be toggled between a file-based and a system-based mode 

  1299.   which determines whether the root of the structure tree is the current file or 

  1300.   the project root.  </li>

  1301.   <li>The signatures of tree nodes have been improved and several new node 

  1302.   associations are now navigable.  </li>

  1303.   <li>A depth slider for controlling tree-expansion has been added.</li>

  1310.   <li>Changes:</li>

  1311.   <li>Inline annotations support have been improved and made consistent with the 

  1312.   structure tree (annotations only show up for intra-declaration structure).</li>

  1313.   <li>The current structure view persists across IDE launches.</li>

  1343.   <li>For AJDEE, compatibility with JDEE 2.2.9beta4. Also, fixes in completion,

  1344.       ajdoc launch, and speedbar.</li>

  1345. </ul>

  1346. 

  1347. <h3><a name="1.0rc3ajdoc">AJDoc</a></h3>

  1348. 

  1349. <p>Some of the more obvious NullPointerException bugs in Ajdoc were fixed, but

  1350. Ajdoc does not implement all the functionality of Javadoc and has some bugs:</p>

  1351. <ul>

  1352.   <li>Split indexes do not work correctly</li>

  1353.   <li>Inner classes are not listed in indexes </li>

  1354.   <li>Synthetic methods are documented</li>

  1355.   <li>There is no package frame even when packages are specified on the command line</li>

  1356.   <li>-group option is not implemented</li>

  1357.   <li>-use targets are not all calculated correctly</li>

  1358.   <li>Exception information may not be printed for the @throws tag</li>

  1359.   <li>Verbose output should go to stderr, not stdout</li>

  1360.   <li>Extra links are generated (should be unlinked text) </li>

  1361. </ul>

  1362. <p>Further, Ajdoc has not been testing on variants of the J2SE (it uses javadoc classes).

  1363. 

  1364. <h3><a name="1.0rc3taskdefs">Ant taskdefs</a></h3>

  1365. <p>The Ajc taskdef was updated to support the new compiler options and the .aj extension,

  1366. and some NullPointerException bugs were fixed (thanks to Vincent Massol for a bug

  1367. report listing the line number of the fix).  The AJDoc cannot be run repeatedly

  1368. in a single Ant run, and has trouble loading the doclet unless the libraries

  1369. are installed in ${ant.home}/lib.

  1480. implementable on current JVMs without memory leaks (this wasn't true

  1481. of the previous version).  Most people will probably not notice these

  1482. changes, but the correct semantics are described in

  1483. <a href="progguide/semantics.html">the semantics section of the programming

  1484. guide</a>.

  1485. </p>

  1486. 

  1487. <p>In a related change, aspects are not allowed to implement either

  1488. the <code>java.io.Serializable</code> or the

  1489. <code>java.lang.Cloneable</code> interface.  It is unclear what the

  1490. correct behavior of a system should be when an aspect is serialized or

  1491. cloned, and rather than make an arbitrary choice right now we've

  1492. chosen to leave the most room to design them right in a future

  1493. release.</p>

  1494. 

  1495. <h2><a name="1.0rc1compiler">Compiler</a></h2>

  1496. 

  1497. <p>ajc now directly generates .class files without using javac as a

  1498. back-end.  This should result in improved compiler performance, better

  1499. error messages and better stack-traces and debugging info in those

  1500. .class files.  -preprocess mode is still available for those who want

  1501. to generate legal Java source code and a new -usejavac mode is

  1502. available if you have a requirement to continue to use javac as a

  1503. back-end.</p>

  1504. 

  1505. <p>ajc now officially supports source files with the .aj extension.

  1506. We plan to extend this support to the rest of our tools as time

  1507. permits.

  1508. </p>

  1509. 

  1510. <p>This release of ajc includes support for the "-source 1.4" option

  1511. that enables the new 'assert' keyword in jdk1.4.  This option only

  1512. works correctly when compiling against the jdk1.4 libraries.  In

  1513. addition, this release of ajc will run under SUN's jdk1.4beta2.

  1514. However, we still strongly recommend that most users use the non-beta

  1515. jdk1.3.</p>

  1717. 

  1718. <p> There have been many changes to make the 1.0 language both simpler

  1719. and more powerful.  User feedback has driven most of these design

  1720. changes.  Each email we've received either making a suggestion or just

  1721. asking a question about a confusing part of the language has played a

  1722. part in shaping this design.  We'd like to thank all of our users for

  1723. their contributions.

  1724. 

  1725. <p>While we don't have room to thank all of our users by name, we'd

  1726. like to specifically mention a few people for their high-quality

  1727. sustained contributions to the users@aspectj.org mailing list as well

  1728. as through their feature requests and bug reports.  Robin Green

  1729. (who'll be very happy to see <code>declare error</code>), Stefan

  1730. Hanenberg (who should appreciate the '+' wildcard in type patterns),

  1731. and Rich Price (who suggested final pointcuts, more flexible

  1732. dominates, and many other improvements).<p>

  1733. 

  1734. <p> Note that entries into the <a href="porting.html">porting

  1735. notes</a> for this release are linked from the various language

  1736. changes.  </p>

  1737. 

  1738. <h4>Pointcuts</h4>

  1739. 

  1740. <p> Perhaps the least interesting -- but most pervasive -- change is

  1741. that the names of the single-kinded pointcut designators (the ones

  1742. that pick out only one kind of join point) </p>

  1743. 

  1744. <blockquote>calls executions gets sets handlers initializations

  1745. staticinitializations</blockquote>

  1746. 

  1747. <p> have been

  1748. <a href="porting.html#1.0a1-plural-to-singular">changed</a> to be

  1749. singular rather than plural nouns </p>

  1750. 

  1751. <blockquote>call execution get set handler initialization

  1752. staticinitialization</blockquote>

  1753. 

  1754. <p> Although a side benefit is that the names are one character

  1755. shorter, the real benefit is that their combination with the

  1756. <CODE>&amp;&amp;</CODE> and <code>||</code> operators now reads much

  1757. more naturally.  No longer does "and" mean "or" and "or" mean "and".

  1758. </p>

  1759. 

  1760. <p> You'll notice that <code>receptions</code> doesn't appear on the

  1761. table as being shortened to <code>reception</code>.  That's because

  1762. call and reception join points have been merged, and the

  1763. <code>receptions</code> pointcut declaration has been

  1764. <a href="porting.html#1.0a1-remove-receptions">eliminated</a>.  Now,

  1765. <code>call</code> join points describe the action of making a call,

  1766. including both the caller and callee.  Eliminating reception join

  1767. points makes AspectJ much simpler to understand (reception join points

  1768. were a commonly misunderstood feature) without giving up expressive

  1769. power.</p>

  1770. 

  1771. <p> We have <a href="porting.html#1.0a1-fixing-state-access">changed

  1772. the mechanism for accessing state</a> at join points, which has the

  1773. benefit of making our treatment of signatures

  1774. <a href="porting.html#1.0a1-no-subs-in-sigs">cleaner</a> and easier to

  1775. read.  As a part of this, the <code>instanceof</code> pointcut

  1776. designator has now been

  1777. <a href="porting.html#1.0a1-fixing-instanceof">split into two

  1778. different pointcut designators</a>, <code>this</code> and

  1779. <code>target</code>, corresponding to a join point's currently

  1780. executing object and target object, respectively.  </p>

  1781. 

  1782. <p> The new <code>args</code> pointcut adds expressive power to the

  1783. language by allowing you to capture join points based on the actual

  1784. type of an argument, rather than the declared type of its formal.  So

  1785. even though the <code>HashSet.removeAll</code> method takes a

  1786. <code>Collection</code> as an argument, you can write advice that only

  1787. runs when it is actually passed a <code>HashSet</code> object. </p>

  1788. 

  1789. <p> AspectJ's notion of object construction and initialization, a

  1790. complicated process in Java, has been clarified.  This affects some

  1791. uses of the

  1792. <a href="porting.html#1.0a1-initializations">initializations

  1793. pointcut</a> and

  1794. <a href="porting.html#1.0a1-constructor-calls">constructor calls</a>

  1795. pointcut.  </p>

  1796. 

  1797. <p> The little-used pointcuts

  1798. <a href="porting.html#1.0a1-hasaspect"><code>hasaspect</code></a> and

  1799. <a href="porting.html#1.0a1-withinall"><code>withinall</code></a> have

  1800. been removed. </p>

  1801. 

  1802. <p> The <code>returns</code> keyword is

  1803. <a href="porting.html#1.0a1-user-defined-returns">no longer

  1804. necessary</a> for user-defined pointcuts.  </p>

  1805. 

  1806. <p> Pointcuts may now be declared <code>static</code>, and

  1807. <a href="porting.html#1.0a1-static-pointcuts">only static

  1808. pointcuts</a> may be declared in classes and referred to with

  1809. qualified references (such as <code>MyAspect.move()</code>).  </p>

  1810. 

  1811. <p> Non-abstract pointcuts may now be declared <code>final</code>.

  1812. </p>

  1813. 

  1814. <p> We have finally added an extremely general pointcut,

  1815. <code>if(<var>BooleanExpression</var>)</code>, that picks out

  1816. join points programatically.  </p>

  1817. 

  1818. 

  1819. <h4>Type patterns</h4>

  1820. 

  1821. <p> Our treatment of

  1822. <a href="porting.html#1.0a1-new-wildcards">* and ..</a> in type

  1823. patterns is cleaner.  </p>

  1824. 

  1825. <p> Type patterns now have the ability to include array types, and

  1826. there is a new wildcard, +, to pick out all subtypes of a given type.

  1827. Previously, the subtypes operator was only allowed in introduction,

  1828. and was <a href="porting.html#1.0a1-subtypes-to-plus">spelled

  1829. differently</a>.  </p>

  1830. 

  1831. <h4>Advice</h4>

  1832. 

  1833. <p> Around advice is treated much more like a method, with a

  1834. <a href="porting.html#1.0a1-around-returns">return value</a> and an

  1835. optional <a href="porting.html#1.0a1-around-throws">throws clause</a>.

  1836. </p>

  1837. 

  1838. <p> The advice precedence rules have been

  1839. <a href="porting.html#1.0a1-advice-precedence">changed</a>.  Now, for

  1840. example, a piece of after advice that appears lexically later than

  1841. another piece of after advice will run later, as well.  Previously,

  1842. the relationship was the other way around, which caused no small

  1843. amount of confusion.  </p>

  1844. 

  1845. <p> After returning advice has lost a

  1846. <a href="porting.html#1.0a1-after-returning">useless set of

  1847. parentheses</a> when not using the return value. </p>

  1848. 

  1849. <p> The <code>thisStaticJoinPoint</code> reflective object has been

  1850. <a href="porting.html#1.0a1-this-static-join-point">renamed</a>, and

  1851. the <code>thisJoinPoint</code> object hierarchy has been

  1852. <a href="porting.html#1.0a1-this-join-point">simplified</a>.  </p>

  1853. 

  1854. <h4>Introduction and static crosscutting</h4>

  1855. 

  1856. <p> On the static side of the language, introduction hasn't changed,

  1857. but there is now a new keyword, <code>declare</code>, that is used to

  1858. declare various statically-crosscutting properties.  One of these

  1859. properties is subtyping, so we've

  1860. <a href="porting.html#1.0a1-plus-implements-extends">gotten rid of</a>

  1861. the ugly keywords <code>+implements</code> and

  1862. <code>+extends</code>. </p>

  1863. 

  1864. <p> We have provided two new forms, <code>declare error</code> and

  1865. <code>declare warning</code>, for the often-asked-for property of

  1866. compile-time error detection based on crosscutting properties. </p>

  1867. 

  1868. <p> AspectJ's interaction with checked exceptions is now firmly on the

  1869. side of static crosscutting, since Java treats such exceptions at

  1870. compile-time. A new form, <code>declare soft</code>, can be used to

  1871. "soften" checked exceptions into an unchecked form.  This may affect

  1872. some uses of <a href="porting.html#1.0a1-now-use-soft">around

  1873. advice</a> that previously mucked with the exception checking

  1874. system.</p>

  1875. 

  1876. <h4>Aspects</h4>

  1877. 

  1878. <p> The "of each" modifiers have been

  1879. <a href="porting.html#1.0a1-aspects">renamed</a>.  Apart from the

  1880. spelling, the main interesting difference is the splitting up of

  1881. <code>of eachobject</code> into two different modifiers, parallel with

  1882. the split of <code>instanceof</code> into <code>this</code> and

  1883. <code>target</code>.  </p>

  1884. 

  1885. <p> The <code>dominates</code> keyword now takes a type pattern,

  1886. rather than a type.  This allows an aspect A, for example, to declare

  1887. that its advice should dominate the advice of another aspect B as well

  1888. as its subtypes, with the new + subtypes operator: <code>aspect A

  1889. dominates B+</code>.

  1891. 

  1892. <h3><a name="1.0alpha1compiler">Compiler</a></h3>

  1893. 

  1894. <p> The most important change in the compiler is that it supports the

  1895. new language.  In addition, all reported bugs in the last release have

  1896. been fixed.  Thanks for your bug reports.</p>

  1897. 

  1898. <p>The compiler also gets a new <code>-encoding</code> flag in this

  1899. release for handling source files that are not in standard US-ASCII

  1900. format.  Thanks to Nakamura Tadashi for both suggesting this feature

  1901. and for submitting a nice patch to implement it.

  1902. 

  1903. <h4>Known Limitations</h4>

  1904. 

  1905. <p> The previous compiler's limitations regarding join points that

  1906. occurred in anonymous classes have all been eliminated.

  1907. Unfortunately, eliminating this restriction has resulted in

  1908. preprocessed source code that is less readable than in previous

  1909. releases.  More care will be taken in the next release to mitigate

  1910. this effect.  </p>

  1911. 

  1912. <p> Many semantic errors are not caught by ajc but fall through to

  1913. javac.  Moreover, some errors regarding the initialization of final

  1914. fields might never show up when using ajc.  This will be fixed

  1915. shortly.  </p>

  1916. 

  1917. 

  1918. <h3><a name="1.0alpha1documentation">Documentation</a></h3>

  1919. 

  1920. <p> Although we spent much of our time this release cycle updating the

  1921. documentation to the new language rather than improving its content,

  1922. we did make some structural improvements.  The old <cite>Primer</cite> has been

  1923. split into a <cite>Programming Guide</cite>, covering the language, and a

  1924. <cite>Development Environment Guide</cite>, covering the develompent tools.  In

  1925. addition, printable versions of both guides (in PDF) are finally

  1926. included in the documentation package.  </p>

  1927. 

  1928. <h3><a NAME="1.0alpha1ajdoc">Ajdoc</a></h3>

  1929. 

  1930. <p> Ajdoc was rewritten to conform with the language changes and provide support

  1931. for other AspectJ/Java compilers.  Our doclet is used by default creating

  1932. AspectJ-specific documentation, or Sun's standard doclet can be used by

  1933. passing the '-standard' flag to Ajdoc to produce regular Javadoc documentation

  1934. (excluding AspectJ-specifics).

  1935. </p>

  1936. 

  1937. <h3><a NAME="1.0alpha1ant">Ant</a></h3>

  1938. 

  1939. <p> An Ajdoc task is now available.  The Ajc ant task was improved to

  1940. be completely back-compatible with the Javac task.</p>

  1941. 

  1942. <h3><a NAME="1.0alpha1ajbrowser">AJBrowser</a></h3>

  1943. 

  1944. <p> The "AspectJ Browser" is a new standalone source code browsing application.

  1945. It will let you compile ".lst" files, view the structure for those files and

  1946. navigate the corresponding source code.</p>

  1947. 

  1948. <h3><a name="1.0alpha1ajde">AJDE</a></h3>

  1949. 

  1950. <h4>AJDE for JBuilder</h4>

  1951. 

  1952. <h5>Installation</h5>

  1953. <ul>

  2017.   be restarted for the AspectJ window to show again.</li>

  2018.   <li>There is no compiler progress dialog--the way to tell if the compile is

  2019.   finished is to watch the "status" area of the main window.</li>

  2020.   <li>There are no keyboard compile/execute shortcuts.</li>

  2021.   <li>The structure view is not persistent between IDE launches--you must
