[jbossts-issues] [JBoss JIRA] (JBTM-2409) XARecoveryModuleHelpersUnitTest hang

XARecoveryModuleHelpersUnitTest hang ------------------------------------ Key: JBTM-2409 URL: https://issues.jboss.org/browse/JBTM-2409 Project: JBoss Transaction Manager Issue Type: Bug Components: Recovery Affects Versions: 5.1.1 Reporter: Michael Musgrove Assignee: Tom Jenkinson Priority: Minor Fix For: 5.next Attachments: 32287.jstack The test checks that recovery helpers can be removed at the correct stages during recovery scans. The CI job http://albany.eng.hst.ams2.redhat.com/job/narayana-codeCoverage/196 shows the hang. The junit test thread: - starts 2 threads that will remove a recovery helper - triggers xaRecoveryModule.periodicWorkFirstPass() - triggers xaRecoveryModule.periodicWorkSecondPass() - joins with remover threads The jstack output shows: - the two threads in the process of removing a recovery helper and are waiting for the first pass to finish; - the junit test thread is waiting to join with these two threads; Since both recovery passes must have completed it looks like the remover threads weren't notified when the first pass completed.
