For example, records compiled with preview on JDK 15 cannot be used on JDK 16 without recompilation. This + is a JVM limitation unrelated to AspectJ. Also, e.g. sealed classes are preview-1 on JDK 15 and preview-2 on JDK 16. + You still need to recompile, no matter what. +</p> +<p> +<p> + You can find some sample code in the AspectJ test suite under the respective AspectJ version in which the features + were first supported (possibly as JVM preview features): +</p> +<ul> + <li><a href="https://github.com/eclipse/org.aspectj/tree/master/tests/features195/textblock"> + AspectJ 1.9.5: text blocks</a></li> + <li><a href="https://github.com/eclipse/org.aspectj/tree/master/tests/features196/java14"> + AspectJ 1.9.6: records, <tt>instanceof</tt> patterns</a></li> + <li><a href="https://github.com/eclipse/org.aspectj/tree/master/tests/features197/java15"> + AspectJ 1.9.7: hidden classes, sealed classes</a></li> +</ul> + +<h2>Using LTW on Java 16+</h2> + +<p> + Please note that if you want to use load-time weaving on Java 16+, the weaving agent collides with + <a href="https://openjdk.java.net/jeps/396">JEP 396 (Strongly Encapsulate JDK Internals by Default)</a>. Therefore, + you need to set the JVM parameter <tt>--add-opens java.base/java.lang=ALL-UNNAMED</tt> in order to enable aspect + weaving. This is due to the fact that the weaver uses internal APIs for which we have not found an adequate + replacement yet when defining classes in different classloaders. +</p> + +<h2>Organisational and internal changes</h2> + +<p> + For AspectJ 1.9.7, we implemented a lot of internal changes concerning the build and release process, most of which + are not visible in the product itself but will help us to more easily maintain and release the product in the future + and more easily on-boarding new developers or contributors. For example: +</p> +<ul> + <li>The main repository has been moved to <a href="https://github.com/eclipse/org.aspectj">GitHub</a>, i.e. you can + open bug reports, feature requests and pull requests there now.</li> + <li>The Maven build has been improved, i.e. it is now easier to build and contribute to the product. Developers can + just import the Maven project and no longer depend on Eclipse to build and test AspectJ, but can e.g. also use + IntelliJ IDEA.</li> + <li>Continuous integration builds now run on GitHub for different JDK versions, also for pull requests. I.e. both + maintainers and contributors get to know if their changes break any tests.</li> + <li>We can build releases and deploy them directly to Sonatype OSSRH (snapshots) or Maven Central (releases) with + Maven now, i.e. it should be much easier in the future to publish development versions in order to enable users to + re-test fixed bugs or try new features.</li> + <li>All tests are portable now, i.e. they correctly run on Windows, too. This enables developers and contributors to make + a choice if they want to work on Linux or on Windows.</li> +</ul> + +<h2>Other changes and bug fixes</h2> + +<ul> + <li>Remove legacy JRockit support.</li> + <li>Support Windows 10 and Windows Server 2016/2019 in installer. Those versions were not detected until now, which + led to bogus Windows batch files forwarding only 9 AJC parameters to the Java process via + <tt>%1 %2 %3 %4 %5 %6 %7 %8 %9</tt> instead of <tt>%*</tt>.</li> + <li>AJdoc (AspectJ's javadoc generator add-on for aspects) now supports the JDK 16 javadoc generator.</li> + <li>Fix <tt>serialVersionUID</tt> initialization for Java 9+</li> + <li>AJC (AspectJ Compiler) usage texts sometimes used to be printed twice and they were printed too often, e.g. on + top of every compile error. This has been fixed. Furthermore, the partly outdated usage text is now basically the + same as ECJ (Eclipse Java Compiler), which AJC is a fork of, plus AspectJ-specific additions which are added during + runtime.</li> + <li>Source and javadoc JARs distributed together with the AspectJ artifacts on Maven Central are now more accurate and + more complete with regard to what is included (ASM, JDT Core) and how package names have been relocated.</li> + <li>Fix sample code formatting issues (indentation) throughout the documentation.</li> +</ul> + +<p> + Available: 1.9.7 available ##-###-2021 +</p> + +</body> + +</html> diff --git a/docs/dist/doc/index.html b/docs/dist/doc/index.html index f8309f335..8192f36ac 100644 --- a/docs/dist/doc/index.html +++ b/docs/dist/doc/index.html @@ -138,6 +138,7 @@ <tr> <td>README's </td> <td>Changes and porting guide for AspectJ + <a href="README-197.html">1.9.7</a>, <a href="README-196.html">1.9.6</a>, <a href="README-195.html">1.9.5</a>, <a href="README-194.html">1.9.4</a>, |
