Cannot get delegate of JMSContext during an beforeCompletion synch ------------------------------------------------------------------ Key: WFLY-11450 URL: https://issues.jboss.org/browse/WFLY-11450 Project: WildFly Issue Type: Bug Components: CDI / Weld Affects Versions: 14.0.1.Final, 8.0.0.CR1 Environment: WildFly 14.0.1.Final, narayana 5.9.0.Final WildFly 8.0.0.CR1 Reporter: Jan-Willem Gmelig Meyling Assignee: Matej Novotny Priority: Minor Attachments: ARJUNA016082.log The {{TransactionContext}} registers a {{TransactionScopeCleanup}} {{Synchronization}} with the active transaction. This prevents a {{TransactionContext}} to be opened from another {{beforeCompletion}} {{Synchronization}}, if the transacted {{JMSContext}} was not interacted with earlier in the transaction. (Because the synchronization cannot be placed) *Use case* I have a JPA post insert lifecycle listener that needs to publish an event. I'd like this to happen within the same XA transaction. The lifecycle listener is handled in during the pre-commit flush, itself invoked through another {{beforeCompletion}} transaction {{Synchronization}}. *Workaround* Flush the {{EntityManager}} and don't leave the flushing up to the {{beforeCompletion}} synchronization. The issue seems also described in the following Stack Overflow issue: https://stackoverflow.com/questions/21523534/jboss-wildfly-arjuna016082-s... (Which refers to WildFly 8.0.0.CR1) Back in the day, it seemed [~smarlow] suggested that an *interposed* synchronization should be registered with the {{TransactionSynchronizationRegistry}} instead. See the attached log for a full stack trace.
