[JBoss JIRA] Created: (JBPM-2608) JobSession.findJobsWithOverdueLockTime returns incorrect list of overdue jobs for LockMonitorThread

by Martin Putz (JIRA)

JobSession.findJobsWithOverdueLockTime returns incorrect list of overdue jobs for LockMonitorThread --------------------------------------------------------------------------------------------------- Key: JBPM-2608 URL: https://jira.jboss.org/jira/browse/JBPM-2608 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: jBPM 3.2.7, jBPM 3.2.8 Reporter: Martin Putz Assignee: Alejandro Guizar Fix For: jBPM 3.2.9 In org.jbpm.job.executor.LockMonitorThread#unlockOverdueJobs(), the list of overdue jobs to be unlocked is queried the following way: Date threshold = new Date(System.currentTimeMillis() - maxLockTime - lockBufferTime); List overdueJobs = jbpmContext.getJobSession().findJobsWithOverdueLockTime(threshold); But the query is incorrect, as it returns all jobs where the lockTime is bigger than the threshold, which means that the job has been locked shorter than (maxLockTime + lockBufferTime): <query name="JobSession.findJobsWithOverdueLockTime"> <![CDATA[ select job from org.jbpm.job.Job as job where job.lockTime > :threshold ]]> </query> As a result, the LockMonitorThread will set the lockTime and lockOwner to null, where the same Job instance is also updated by a JobExecutorThread, which will lead to a StaleObjectStateException: ERROR [org.hibernate.event.def.AbstractFlushingEventListener] (JbpmJobExector:LockMonitorThread@169.1.1.1) Could not synchronize database state with session org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [org.jbpm.job.ExecuteActionJob#123] The 'where' clause in the query needs to be reversed: Index: modules/core/src/main/resources/org/jbpm/db/hibernate.queries.hbm.xml =================================================================== --- modules/core/src/main/resources/org/jbpm/db/hibernate.queries.hbm.xml (revision 5825) +++ modules/core/src/main/resources/org/jbpm/db/hibernate.queries.hbm.xml (working copy) @@ -385,7 +385,7 @@ <![CDATA[ select job from org.jbpm.job.Job as job - where job.lockTime > :threshold + where job.lockTime < :threshold ]]> </query> -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
