First of all, note that this bug is very linked to bug 6614506 :
   jmx interop regression when Server is over JDK6 and Client over JDK5

Indeed, the problem concerns a remote call to getMBeanInfo using rmi/iiop.
The particularity of this test failure compared to bug 6614506 is that :
1) only model MBean is concerned
2) the test fails for all interop configuration, that is :
- server runs on JDK5 and client on JDK6
- server runs on JDK6 and client on JDK5

For these reasons, I prefer to create another bug.
Then close it as duplicated if needed.

The stack trace on client side is :
