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

[Alexander Schlett (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBPM-983?page=all ]

Alexander Schlett updated JBPM-983:
-----------------------------------

    Attachment: SimpleTest.java

New Version with Join and Fork not being async, other work nodes are "exclusive" now, it still DOESN'T WORK,
please try the attached test case, JobExecutor.nrOfThreads=5
Chances that workflow will never come to an end are high, though sometimes it works.

> 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.
