Re: proxy annotation issue

by Henri Tremblay :: Rate this Message:

Hi,

I'm not a cglib developer but I worked a lot with it. From as far as I
know, this behavior is "normal". cglib will create a proxy that
extends your class. The annotations are still on the base class but
not on the proxy. That's the same behavior as for any class extending
a class with annotations. If you want to know if a method was
annotated in one of its overrides, you need to loop in the complete
hierarchy.

That said, I can see why this feature could be useful. It makes it
easier to replace the class by its proxy. So some flag
"inheritAnnotations" could be useful. That would means a new java 5
only version of cglib thought.

Hope it helps,
Henri
