I have a timer with an action that invokes seam expression, within the action method, I invoke processInstance.suspend(); Seems like the process get suspended, but then, I get the following exception:
20:14:49,781 ERROR [AbstractFlushingEventListener] 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.graph.exe.Token#140] at org.hibernate.persister.entity.AbstractEntityPersister.check(AbstractEntityPersister.java:1765) at org.hibernate.persister.entity.AbstractEntityPersister.update(AbstractEntityPersister.java:2407) at org.hibernate.persister.entity.AbstractEntityPersister.updateOrInsert(AbstractEntityPersister.java:2307) at org.hibernate.persister.entity.AbstractEntityPersister.update(AbstractEntityPersister.java:2607) at org.hibernate.action.EntityUpdateAction.execute(EntityUpdateAction.java:92) at org.hibernate.engine.ActionQueue.execute(ActionQueue.java:250) at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:234) at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:142) at org.hibernate.event.def.AbstractFlushingEventListener.performExecutions(AbstractFlushingEventListener.java:298) at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:27) at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1000) at org.jbpm.persistence.db.DbPersistenceService.flushSession(DbPersistenceService.java:261) at org.jbpm.persistence.db.DbPersistenceService.close(DbPersistenceService.java:200) at org.jbpm.svc.Services.close(Services.java:243) at org.jbpm.JbpmContext.close(JbpmContext.java:133) at org.jbpm.job.executor.JobExecutorThread.executeJob(JobExecutorThread.java:195) at org.jbpm.job.executor.JobExecutorThread.run(JobExecutorThread.java:62) 20:14:49,786 INFO [DbPersistenceService] problem flushing session: optimistic locking failed 20:14:49,786 INFO [Services] optimistic locking failed, could not close service: persistence What causes it and how can I avoid it?
