EJBClient.isEJBProxy method returns false when testing an ejb proxy

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
