[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2124) HibernateException hidden during flush using XA with WAS6

HibernateException hidden during flush using XA with WAS6 --------------------------------------------------------- Key: HHH-2124 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2124 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.1.2, 3.1.3 Environment: Hibernate 3.1.3 Oracle 10G Websphere Application Server 6 Reporter: Ole Dalgaard In an XA environment, using WebSphereExtendedJTATransactionLookup, HibernateExceptions are hidden during flush in this code in CacheSynchronization.java try { if (flush) { log.trace("automatically flushing session"); ctx.managedFlush(); } } catch (RuntimeException re) { setRollbackOnly(); throw re; } After adding some logging to CacheSynchronization.beforeCompletion I got this error message: org.hibernate.HibernateException: Illegal attempt to associate a collection with two open sessions at
