8207908: JMXStatusTest.java fails assertion intermittently

[kevinjwalls]

Test failure, reproducible running batches of tests at the same time on the same machine.
The use of "jcmd TestApp ..." gathers more output than the test wants and than its regexes can handle.

Using the PID to match only the wanted process, my batches of 25 tests at the same time run in parallel without failure.
