Ronald van Kuijk commented on JBPM-983:
---------------------------------------

What I did:
- use CVS version as of today 2007-06-22
- 2 jobexecurtor threads
- Take the non-subproces version
- removed the async=true op de join en fork 
- changed async=true to async=exclusive in node 1 and node 2

Then 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.
