RFR: 8031766: jstatd nightly tests failing with Expected one jstatd process, got 2. Test will be canceled.

[Yekaterina Kantserova]

Hi David,

The tests start a couple of external processes and have a procedure of destroying them if something unexpected happens. But when JVM crashes in the middle of the execution this procedure is useless and processes are left on servers. It should be up to framework to do clean-up. Unfortunately the JTreg framework has no mechanism of removing process trees today. But it has been discussed a lot and hopefully will be implemented in the nearest future.

Best regards,
Katja

Hi Katja,

I don't object to making the test more resilient, but I do have to 
wonder why we have multiple jstatd processes as that would seem to 
indicate another problem that needs addressing.
