That is definitely be an issue for aop. From what I can see of the test, when we add a method to the underlying CtClass the ClassInfo wrapper is not updated. I think the ClassInfo's MethodInfos etc. are cached on first load, and not refreshed at all. One solution would be to add a refresh() method to ClassInfo, but there are probably some other and better solutions too. When I mentioned the MutableClassInfo stuff to Ales, he mentioned adding an AOP view to ClassInfo, MethodInfo etc. containing the new stuff added by AOP, but I am not sure how that would be added since instantiation of all those objects are hidden inside jboss-reflect.
