Christian Kaltepoth updated JBPM-758:
-------------------------------------
Attachment: jbpm_session_already_closed_exception.patch
This patch for jBPM 3.1.2 seems to fix the problem with Hibernate 3.2
> DbPersistenceService needs update for new Hibernate version
> -----------------------------------------------------------
>
> Key: JBPM-758
> URL: http://jira.jboss.com/jira/browse/JBPM-758
> Project: JBoss jBPM
> Issue Type: Bug
> Components: Core Engine
> Affects Versions: jBPM 3.1.2
> Environment: jboss AS 4.0.4, hibernate 3.1 or hibernate 3.2
> Reporter: Thomas Klute
> Assigned To: Tom Baeyens
> Fix For: jBPM 3.1.3
>
> Attachments: jbpm_session_already_closed_exception.patch
>
> Original Estimate: 15 minutes
> Remaining Estimate: 15 minutes
>
> Release of JDBC connections changed with hibernate version > 3.0.
> DbPersistenceService now throws exception when trying to close a hibernate session (because in was closed automatically when the transaction committed).
> The exception happens every few seconds when using the jbpm scheduler-service.
> See below for stack trace.
> See http://www.hibernate.org/250.html#A31 for a detailed description of hibernate-changes regarding JDBC connections.
> FYI: The exception does not roll back the transaction, because it has already been committed.
> Please adapt the code to the new hibernate behaviour. Maybe just comment out the "throw" of the exception.
> I have no idea what code would work with old _and_ new hibernate versions.
> We just got the problem integrating jbpm into a jboss AS 4.0.4 using hibernate 3.2.
