Changes

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:

AJDT Memory usage

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:

-Xset:minimalModel=true,typeDemotion=true

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: + +http://andrewclement.blogspot.com/2010/07/ajdt-memory-usage-reduction.html +

Runtime changes

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: -Xset:targetRuntime1_6_10=true. With that option on +you will need to ensure you run against the aspectjrt.jar from a 1.6.10 build.

The changes are discussed in bug 323438
