as we've stated in the aop design forum (and here) is that the current state of jboss-reflect is too limited for aop to use at all. a well designed MutableClassInfo can change that though. from what i can see it has to support the following: - the possibility to create a classobjectrepresentation from a byte[]/File/Url - be able to change/add/remove fields/methods/constructors/classes similiar to what javassist support - do finegrained operations/checks ala annotation visibility (which is only possible with javassist and not java.lang.reflect afaik) - be able to get a classobjectrepresentations (ala ClassFile in javassist) from an existing ClassInfo object - support scoped classpools ++?
