RFR 9: [testbug] 8168613 : CORBA ObjectStreamTest fails with address in use

[Roger Riggs]

Please review a test fix for an address-in-use problem in this CORBA 
serialization test.
The test is simplified to just communicate client to server via the orb 
in the process.

It does not need activation, a name service, or the orbd to exercise the
necessary serialization implementation.  And therefore, no contention 
for sockets, ports, etc.
