[ https://issues.jboss.org/browse/WFLY-10229?page=com.atlassian.jira.plugin... ] Scott Marlow commented on WFLY-10229: ------------------------------------- [~tomjenkinson] yeah, this is a problem that we noticed with our testing. Let me know if you would like a forward of the private email thread (getting quite long now). Some more details are below. In a test that starts a JTA transaction, invokes an EntityManager.persist operation expected to throw an exception (which marks the transaction for rollback only), however soon after the exception is thrown, the test code now has control and calls entityManager.find() which throws an exception instead of returning null. The first place in Hibernate ORM 5.3, that we go wrong, is getting the transaction status via the TransactionSynchronizationRegistry. Hibernate has the correct TransactionSynchronizationRegistry instance but internally, the TransactionSynchronizationRegistry has a reference to the com.arjuna.ats.jta.TransactionManager, Hibernate gets the incorrect TX status code (1, when status should be 4). Instead the TSR should use org.wildfly.transaction.client.ContextTransactionManager.getStatus(), so that Hibernate goes down the correct code path. Point of failure is: {code} at org.hibernate.engine.transaction.jta.platform.internal.SynchronizationRegistryBasedSynchronizationStrategy.canRegisterSynchronization(SynchronizationRegistryBasedSynchronizationStrategy.java:37) at org.hibernate.engine.transaction.jta.platform.internal.AbstractJtaPlatform.canRegisterSynchronization(AbstractJtaPlatform.java:131) at org.hibernate.resource.transaction.backend.jta.internal.JtaTransactionCoordinatorImpl.pulse(JtaTransactionCoordinatorImpl.java:154) at org.hibernate.internal.AbstractSharedSessionContract.pulseTransactionCoordinator(AbstractSharedSessionContract.java:451) at org.hibernate.internal.AbstractSharedSessionContract.checkTransactionSynchStatus(AbstractSharedSessionContract.java:445) at org.hibernate.internal.SessionImpl.fireLoad(SessionImpl.java:1252) at org.hibernate.internal.SessionImpl.access$1900(SessionImpl.java:206) at org.hibernate.internal.SessionImpl$IdentifierLoadAccessImpl.doLoad(SessionImpl.java:2864) at org.hibernate.internal.SessionImpl$IdentifierLoadAccessImpl.load(SessionImpl.java:2838) at org.hibernate.internal.SessionImpl.find(SessionImpl.java:3473) at org.hibernate.internal.SessionImpl.find(SessionImpl.java:3437) at org.jboss.as.jpa.container.AbstractEntityManager.find(AbstractEntityManager.java:213) {code} -- This message was sent by Atlassian JIRA (v7.5.0#75005)
