just to clear it up. its weakclasscache that cache the ctclasses, the methodinfos are also cached if they have been fetched earlier from what i can tell. one thing we could do is to add a compare(CtClass,CtClass) method and check if there has been any changes after we've fetched the ClassInfo from cache. since we cant do any changes to JavassistTypeInfo, ill add a simple compare(JavassistTypeInfo,CtClass) in JavassistTypeInfoFactoryImpl when we fetch the object from cache and just compare number of methods/fields. - it should be more thorough, but this would do for now i think.
