ive created a aopversion of JavassistTypeInfoFactoryImpl that can be found in the aop project as org.jboss.aop.reflectprototype.JavassistAopTypeInfoFactoryImpl. i made a simple test to make sure that the CtClass isnt frozen (eg the class file is loaded) when creating a ClassInfo object from a CtClass. however, when i try to make some changes to that CtClass and try to load a new ClassInfo object that should reflect the changes the changes isnt there. i recon its because the CtClass is cached in WeakClassCache. can this be an issue for aop? it means that after we get a ClassInfo reference of a CtClass, we cant make changes to that CtClass anymore. imo this would be too restrictive for aop. take a look at the test org.jboss.test.aop.reflectprototype.JavassistAopTypeInfoFactoryImplTestCase for an example.
