Throw EJBException instead of ConcurrentAccessTimeoutException when access attempt of a Session EJB already in a tx by another tx --------------------------------------------------------------------------------------------------------------------------------- Key: WFLY-4834 URL: https://issues.jboss.org/browse/WFLY-4834 Project: WildFly Issue Type: Bug Components: EJB Affects Versions: 10.0.0.Alpha3 Reporter: Brad Maxwell Assignee: Carlo de Wolf Attachments: WFLY-4834.jar EJB3.1 specification chapter *4.6.4 Restrictions for transactions* - A session bean instance can participate in at most a single transaction at a time. - If a session bean instance is participating in a transaction, it is an error for a client to invoke a method on the session object such that the transaction attribute specified in the bean’s metadata annotations and/or the deployment descriptor would cause the container to execute the method in a different transaction context or in an unspecified transaction context. In such a case, the javax.ejb.EJBException will be thrown to a client of the bean’s business interface/ With this flow: - SLSB start with @REQUIRED - SLSB request a reference to a SFSB - call a method SFSB.x() @REQUIRED - call another method SFSB.y() @REQUIRES_NEW It fails with: javax.ejb.ConcurrentAccessTimeoutException: JBAS014360: EJB 3.1 FR 4.3.14.1 concurrent access timeout on org.jboss.invocation.InterceptorContext@4375b1 - could not obtain lock within 5000 MILLISECONDS| It should throw an EJBException as the Session Bean is already participating in a transaction instead of ConcurrentAccessTimeoutException
