Hi rayun, I have exactly the same problem and - thanks for posting - am working on it since last friday. I have built a simple test process and the problem comes in with *even only one timer* - but only when you fork! I have tried the same thing without any forked executions, works fine.
But I only get the StaleObjectStateException, like this: anonymous wrote : | 17:42:59,231 INFO [DbPersistenceService] optimistic locking failed | 17:42:59,247 INFO [Services] problem closing service 'persistence': optimistic locking failed | 17:42:59,309 WARN [ProxyWarnLog] Narrowing proxy to class org.jbpm.job.Timer - this operation breaks == | 17:42:59,341 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.job.Timer#271874] | at org.hibernate.persister.entity.AbstractEntityPersister.check(AbstractEntityPersister.java:1765) | at org.hibernate.persister.entity.AbstractEntityPersister.delete(AbstractEntityPersister.java:2523) | at org.hibernate.persister.entity.AbstractEntityPersister.delete(AbstractEntityPersister.java:2697) | at org.hibernate.action.EntityDeleteAction.execute(EntityDeleteAction.java:74) | 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:146) | 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.hibernate.impl.SessionImpl.managedFlush(SessionImpl.java:338) | at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:106) | at org.jbpm.persistence.db.DbPersistenceService.commit(DbPersistenceService.java:256) | at org.jbpm.persistence.db.DbPersistenceService.close(DbPersistenceService.java:214) | at org.jbpm.svc.Services.close(Services.java:225) | at org.jbpm.JbpmContext.close(JbpmContext.java:139) | at org.jbpm.job.executor.JobExecutorThread.executeJob(JobExecutorThread.java:184) | at org.jbpm.job.executor.JobExecutorThread.run(JobExecutorThread.java:64) | with this process definition: | <process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="simple"> | <start-state name="start"> | <transition to="fork1" name="to_state"> | </transition> | </start-state> | | <state name="first"> | <timer duedate="2 Minutes" name="Wait2Minutes" transition="to_end"> | <action></action> | </timer> | <transition to="join1" name="to_end"> | </transition> | </state> | | <fork name="fork1"> | <transition to="node1"></transition> | <transition to="first" name="to first"></transition> | </fork> | | <join name="join1"> | <transition to="end"></transition> | </join> | | <node name="node1"> | <transition to="join1"></transition> | </node> | | | <end-state name="end"></end-state> | </process-definition> | Your ClassNotFoundException looks to me like you have forgotten to deploy your handler classes together with the process...?!? Maybe can tell more tomorrow.
