[jboss-jira] [JBoss JIRA] (AS7-5888) Errors accessing CMR from ejbStore of the CMP EntityBean (EJB 2.1 spec)

Errors accessing CMR from ejbStore of the CMP EntityBean (EJB 2.1 spec) ----------------------------------------------------------------------- Key: AS7-5888 URL: https://issues.jboss.org/browse/AS7-5888 Project: Application Server 7 Issue Type: Bug Affects Versions: 7.1.1.Final Environment: Windows Reporter: Kamesh Marellapudi Priority: Blocker Labels: jboss Background :: We are trying to upgrade our app from JBoss 4.0.1Sp3 to Jboss 7.1.1-Final. We have a lot of entity beans based on EJB 2.1 spec. We are noticing the following when we run our application on Jboss 7.1.1-Final. We did NOT have these issues on Jboss 4.0.1. Issue :: : ARJUNA016082: Synchronizations are not allowed! Transaction status isActionStatus.RUNNING What I found? 1. In our application we access CMRs of an entity bean from the ejbStore of the same entity bean. 2. ejbStore is invoked from the beforeCompletion of EntityBeanSynchronizationInterceptor$EntityBeanSynchronization. 3. During the invocation of CMR on the entity bean the call gets delegated to JDBCCMRFieldBridge.getrelationSet(). In this method we have the following try { // get the current transaction CmpEntityBeanComponent component = getJDBCStoreManager().getComponent(); TransactionManager tm = component.getTransactionManager(); Transaction tx = tm.getTransaction(); // if whe have a valid transaction... if (tx != null && (tx.getStatus() == Status.STATUS_ACTIVE || tx.getStatus() == Status.STATUS_PREPARING)) { // crete the relation set and register for a tx callback relationSet = new RelationSet(JDBCCMRFieldBridge.this, ctx, setHandle, false); TxSynchronization sync = new TxSynchronization(FieldState.this); tx.registerSynchronization(sync); } else { // if there is no transaction create a pre-failed list relationSet = new RelationSet(JDBCCMRFieldBridge.this, ctx, new List[1], false); } return relationSet; } catch (SystemException e) { throw MESSAGES.errorCreatingRelationSet(e); } catch (RollbackException e) { throw MESSAGES.errorCreatingRelationSet(e); } So we are trying to register TxSynchronization from beforeCompletion of EntityBeanSynchronization. 4. Now in the TwoPhaseCoordinator.addSynchronization method we have the following piece of code // disallow addition of Synchronizations that would appear // earlier in sequence than any that has already been called // during the pre-commmit phase. This generic support is required for // JTA Synchronization ordering behaviour if(sr instanceof Comparable && _currentRecord != null) { Comparable c = (Comparable)sr; if(c.compareTo(_currentRecord) != 1) { return AddOutcome.AR_REJECTED; } } and the SynchronizationImple.compareTo has the following public int compareTo(Object object) { SynchronizationImple other = (SynchronizationImple)object; if(this._isInterposed && (!other._isInterposed)) { return 1; } else if((!this._isInterposed) && other._isInterposed) { return -1; } else if(this._theUid.equals(other._theUid)) { return 0; } else { return this._theUid.lessThan(other._theUid) ? -1 : 1; } } So basically what I understood is the TxSynchronization registration from ejbStore is a bit too late because we are already in the beforeCompletion of one of the synchronizations listed in the transaction unless its registered through TransactionSynchronizationRegistry.registerInterposedSynchronization.
