-----------------------------------------------------------------------------------------------------------

                 Key: HARMONY-4249
                 URL: https://issues.apache.org/jira/browse/HARMONY-4249
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Ilya Leviev


Race conditions at "lazyexceptionopt.cpp":(87-224) at doLazyExceptionOpt() function


TC report on thread unsafe access that result in race condition that occur during concurrent
execution of doLazyExceptionOpt() function


if it low priority issue  I will mark it as expected race condition.
