> 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.
