[jboss-jira] [JBoss JIRA] Commented: (JBPM-983) concurrent process execution fails

[Edward Staub (JIRA)]

Edward Staub commented on JBPM-983:
-----------------------------------

I'm still working on it, but I believe the StaleObjectStateException happens because the job started on the child process, and the Join on the parent process is happening on the same job without respecting exclusivity.  

More later...

> concurrent execution of async nodes with multiple JobExecutor threads fails. the effect is:
> 1) job sync within JobExecutor fails due to org.hibernate.StaleObjectStateException
> 2) process gets stuck in join node and never ends
> junit test for this is attached, it's a simple process with just a fork and a join and some scripts inbetween.
