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.
