When EJB client from 7.1.0.CR2 runs against a 7.0.0 server and an invocation throws an exception, on the client side, something like this shows up (this is an example for a RuntimeException thrown, but it can be any exception, and it doesn't matter if it is thrown by the EJB itself or occurs somewhere during processing):

The impact is that the client receives an unexpected exception and it's impossible for the client side code to introspect the real exception that was received from the server.

This is a regression in CR2 (note that CR1 client doesn't work at all against EAP 7.0.0 due to ~~JBEAP-12882~~).
