I've got the pool/repository stuff moved into javassist, and have created a javassist 3.3.0.snapshot and jboss retro 1.0.2.snapshot. AOP wraps/extends this pool as needed for the extra functionality. The tests now pass on my machine, and I am in a position to have a pure jdk 5 codebase using jboss retro to run with jdk 1.4. I'll need to "re-annotate" some of the tests, i.e use JDK 5 annotations w/ retro instead of the annotationc JDK 1.4 ones. Annotationc can be kept alive for a while, since annotions compiled in by that are readable by the retroed aop code. Meaning we have two ways to annotate code for use with AOP 1. JDK 5 code and jboss retro | @Foo | public class Blah{ | Set<String> test; | } | 2. JDK 1.4 code and annotationc | /** | *@(a)org.acme.Foo{ | */ | public class Blah{ | Set test; | } | I'll keep this on hold for a few days, so if anybody can think of any issues with this switch to JDK 5 speak now View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3957908#...
