[jira] [Created] (GEODE-7959) Improve ConcurrentTestRunner in heavily loaded environment

Kirk Lund created GEODE-7959:
--------------------------------

             Summary: Improve ConcurrentTestRunner in heavily loaded environment
                 Key: GEODE-7959
                 URL: https://issues.apache.org/jira/browse/GEODE-7959
             Project: Geode
          Issue Type: Improvement
            Reporter: Kirk Lund


Upgrading to Mockito 3.x seems to have trouble with tests using ConcurrentTestRunner. The result is many threads trying to capture thread stacks in invocation of mock methods.

Review of code in ConcurrentTestRunner and LoopRunner shows reveals some issues we should improve:
* LoopRunner.execute has a hot busy while loop
* the inner for-loop of LoopRunner.runTestMethod eats exceptions without reporting them
