TEST_BUG: java/rmi/reliability/benchmark fails intermittently because of use of fixed port

TESTFAIL:java/rmi/reliability/benchmark/runRmiBench.sh

The regression test java/rmi/reliability/benchmark/runRmiBench.sh can fail because it uses a fixed port. If this port is already in use by something else on the system, the test will fail.

Basically the runRmiBench.sh script uses a hardcoded port of 2007, and it passes this port value to both the client and server JVMs. If this port is already in use, the server will fail to start, and the client will fail because it cannot connect.

This occurred recently in a JPRT integration run. The log is below.

Either a port should be reserved in java/rmi/testlibrary, or a random unused port should be chosen and then passed to both the client and the server.
