Summary: returned remote reference not reachable

Initial Comment:
If a remote object reference is returned by a 
enterprise bean method, it sometimes is not reachable -
 calling its methods will result in the 
NoSuchObjectException being thrown.  This happens with 
unpredictable frequency.

It seems that this bug is due to the way JBoss 
implements EJB.  ContainerInvoker wrapps all return 
objects with MarshalledObject  - thus if a EJB method 
returns a remote object stub via MarshalledObject, the 
server remote object immediately become out of scope 
and GCable.  Whether a client can use this remote 
reference totally depends on whether GC has a chance 
to collect the remote object on the server.
