Thanks for the quick answer, that made the trick. I didn't realize there's a subclass I can cast Signature to, but it makes sense now.

how about this:

before(): execution(* C.foo(..)) {
   ÂMethodSignature sig = (MethodSignature)thisJoinPoint.getSignature();

   Âfor (Class clazz: clazzes) {
       ÂSystem.out.println(clazz.getName());
