RFR for JDK-7190106 RMI benchmark fails intermittently because of use of fixed port

[Joe Darcy]

Hi Tristan,

Without commenting on the specifics of this test, in my estimation we 
should strongly favor rewriting shell tests as Java programs, as has 
already largely been done in the langtools area:

Based on my research, it looks like the issue of fixed port was already addressed by Stuart Marks in other RMI tests which are Java based. I would like to reuse his solution, however it does not work for shell based tests. Given this,

If we convert the shell script into Java based test, it would avoid using "sleep 10" mechanism to allow for server and client to start up and also give us better control in synchronizing server and client.
