> 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.
