RFR 8057149: sun/management/jmxremote/startstop/JMXStartStopTest.java fails with "Starting agent on port ... should report port in use"

[Staffan Larsen]

I think we should add some logging to say that we are retrying.

nit: some weird indention on line 623.

Otherwise looks good.

Some of the tests use a server socket to simulate starting the agent with the desired port not being available. However, it seems that in certain situations the agent does not provide a conscious error message and fails with RuntimeException instead. This seems to be timing related and therefore the solution is to retry the 'jcmd' command a few times with a delay to provide some cushion for the timing related problems.
