      Description

      java/lang/ThreadGroup/Stop.java fails intermittently, even after JDK-8132548
      But now looks like not test issue anymore.

      ----------System.err:(15/874)----------
      java.lang.InterruptedException

      The exception is from Thread.join(), from line 65:
              // Launch two threads as part of the same thread group
              first.start();
              second.start();

              // Check that the second thread is terminated when the
              // first thread terminates the thread group.
      65: second.join();
              // Test passed - if never get here the test times out and fails.


      Also note that .jtr log shows the "main" elapsed 120 seconds:

      ...
      #section:main
      ----------messages:(4/123)----------
      command: main Stop
      reason: Assumed action based on file name: run main Stop
      Mode: agentvm
      elapsed time (seconds): 120.005

      ...

      Is the "main" (and all) thread be Interrupted by jtreg? (120 seconds is the jtreg "default timeout" )
