TestMixedLockManagerLockPermutation: Timing issue determines the pass/no-pass of the test case
----------------------------------------------------------------------------------------------

                 Key: OPENJPA-1753
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1753
             Project: OpenJPA
          Issue Type: Bug
    Affects Versions: 2.1.0
            Reporter: Fay Wang
            Priority: Minor
             Fix For: 2.1.0
         Attachments: trace_fail.txt, trace_success.txt

This test case spawns three threads and the pass/no pass of the test cases depends on the
timing. 

	One example is TestMixedLockManagerFindPermutation.testFindReadPessimisticRead: 
        commonFindTest(
            "testFind(Read,Commit/PessimisticRead,Rollback)",
            LockModeType.READ, Act.CommitTx, 1, null,
            LockModeType.PESSIMISTIC_READ, Act.RollbackTx, 1, null);

	If the find by the second child [Thread-8] is executed before the jdbc commit of the update
statement by the first child [Thread-7], the test will fail. Attached are the trace file for
the successful run and failing run.
