How to unwrap the original object from a dynamic proxy

Question

what\'s the best approach to unwrap a dynamic proxy to retrieve the original object beneath? The dynamic proxy has been created using java.lang.reflect.Proxy.newProxyI

Answer 1

Each proxy has an InvocationHandler associated with it. Only the InvocationHandler knows which object (if any) underlies the proxy. If you control the creation of the proxy, then you can supply your own InvocationHandler that will have the extra functionality that you desire (i.e. will be able to disclose the underlying object.) If you don't, then I am afraid you're out of luck.
