RFR 8184445: JShell tests: fail intermittently if tests are run in high concurrent mode.

[joe darcy]

Hi Robert,

The fix looks acceptable in terms of addressing the problem, but is 
there a sense of how this might impact running time of the test suite?

Phrased differently, are there plans to make the tests more robust to 
concurrent runs in the future?

Thanks,

-Joe
