- <h1>AspectJ 1.6.10 Readme</h1>
-
- <p>The full list of resolved issues in 1.6.10 is available <a href="https://bugs.eclipse.org/bugs/buglist.cgi?query_format=advanced;bug_status=RESOLVED;bug_status=VERIFIED;bug_status=CLOSED;product=AspectJ;target_milestone=1.6.10;target_milestone=1.6.10M1;target_milestone=1.6.10M2;target_milestone=1.6.10RC1">here</a></h2></p>

- <h2>Changes</h2>
- <p>1.6.10 is primilarily just bug fixes for AspectJ, mainly in the areas of ITDs and generic aspects. However, there are a couple
- of important changes that users ought to be aware of:</p>
- <h3>AJDT Memory usage</h3>
- <p>Type demotion has been in use during loadtime weaving for a while now, this enables the load time weavers to discard state
- and recover it at a later time (and so generally run with a smaller memory footprint). Type demotion is now supported under AJDT
- in Eclipse and will enable AJDT to run with smaller heaps. This feature is still experimental and needs turning ON if you want
- to try it out. To turn it on, open your AspectJ project properties in eclipse and in the AspectJ Compiler section, scroll down to 'Other' and
- in the non-standard compiler options setting, specify:</p>
- <pre><tt>-Xset:minimalModel=true,typeDemotion=true</tt></pre>
- <p>If I can get enough positive feedback about this option, it will be made the default. For a more detailed write up, check out
- the blog post:

- </p>
- <h3>Runtime changes</h3>
- <p>A big thank you to Abraham Nevado and his team who have been working on some issues to optimize loadtime weaving and the
- code generated by AspectJ. 1.6.10 includes some new changes to the aspectjrt.jar. The changes are new methods that enable
- the woven code to be a little shorter/neater. As we want to continue to have compatibility with older aspectjrt.jar a user needs to
- choose to activate these optimizations by specifying the option: <tt>-Xset:targetRuntime1_6_10=true</tt>. With that option on
- you will need to ensure you run against the aspectjrt.jar from a 1.6.10 build.</p>
- <p>The changes are discussed in <a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=323438">bug 323438</a></p>
