[build-test][classlib-test] uncaught exceptions in Concurrent Tests
-------------------------------------------------------------------

                 Key: HARMONY-5972
                 URL: https://issues.apache.org/jira/browse/HARMONY-5972
             Project: Harmony
          Issue Type: Bug
         Environment: All
            Reporter: Chunrong Lai



  The concurrent tests have been enabled since commit r691476 and uncaught exceptions are
observed there. The stacktrace is as below 

run-tests:
    [junit] Running ExecutorsTest
    [junit] Uncaught exception in pool-12-thread-1:
    [junit] junit.framework.AssertionFailedError
    [junit]     at junit.framework.Assert.fail(Assert.java:47)
    [junit]     at junit.framework.Assert.assertTrue(Assert.java:20)
    [junit]     at junit.framework.Assert.assertTrue(Assert.java:27)
    [junit]     at JSR166TestCase.threadAssertTrue(JSR166TestCase.java:218)
    [junit]     at ExecutorsTest$2.run(ExecutorsTest.java:405)
    [junit]     at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:643)
    [junit]     at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:668)
    [junit]     at java.util.concurrent.Executors$PrivilegedThreadFactory$1$1.run(Executors.java:575)
    [junit]     at java.security.AccessController.doPrivilegedImpl(AccessController.java:171)
    [junit]     at java.security.AccessController.doPrivileged(AccessController.java:64)
    [junit]     at java.util.concurrent.Executors$PrivilegedThreadFactory$1.run(Executors.java:572)
    [junit]     at java.lang.Thread.run(Thread.java:670)
    [junit] Tests run: 32, Failures: 1, Errors: 0, Time elapsed: 2.258 sec
    [junit] Test ExecutorsTest FAILED
   when we do single test with (at directory of working_classlib) "ant -Dtest.jre.home=...\drlvm\...\jdk\jre
-Dtest.case=ExecutorsTest test"

  The failures are platform-dependent. Although ExecutorsTest fails in all of the platforms
(with drlvm),  ReentrantLockTest, AbstractQueuedSynchronizerTest and ScheduledExecutorTest
only fail in some platforms.
  RI performs better but also not perfect here. It just pass ExecutorsTest but also fails
in ReentrantLockTest. It is also noted that the failure from RI is an assertion instead of
the uncaught exception.
