Need to investigate why isEJBProxy returns false in the following case, and add tests for this method.

I've borrowed the code from EJBClient.isEJBProxy(), and it's not doing what I expected:

22:24:23,819 INFO [stdout] (default task-1) object.getClass(): class de.example.GreeterResource$$$view1
22:24:31,609 INFO [stdout] (default task-1) Proxy.isProxyClass(object.getClass()): false

So GreeterResource$$$view1 isn't a proxy, even though its String representation is:

Proxy for view class: de.example.GreeterResource of EJB: GreeterResource
