[jboss-jira] [JBoss JIRA] Commented: (JBPM-983) concurrent process execution fails
[ http://jira.jboss.com/jira/browse/JBPM-983?page=comments#action_12375366 ]
Tom Baeyens commented on JBPM-983:
----------------------------------
about the exclusive feature. the idea is that the correctness of a process should depend
on locking (optimistic by default or pessimistic programmaticaly). the exclusive is just
an indication to the engine that the exclusive jobs will probably cause interference and
result in stale object exceptions that will have to be rolled back. so the exclusive is
just an optimisation that can be used to get less optimistic locking failures.

----------------------------------
Key: JBPM-983
URL: http://jira.jboss.com/jira/browse/JBPM-983
Project: JBoss jBPM
Issue Type: Bug
Components: Core Engine
Affects Versions: jBPM jPDL 3.2
Environment: Hypersonic in-memory database, JobExecutor configured with 5
threads
Reporter: Alexander Schlett
Assigned To: Tom Baeyens
Priority: Critical
Fix For: jBPM jPDL 3.2.2
Attachments: SimpleTest.java, SimpleTest.java, SimpleTest.java, SimpleTest.java,
SimpleTest.java
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.
