Transaction automatically started for MDB even though it uses BMT ----------------------------------------------------------------- Key: AS7-6441 URL: https://issues.jboss.org/browse/AS7-6441 Project: Application Server 7 Issue Type: Bug Components: EJB Affects Versions: 7.1.3.Final (EAP) Reporter: Justin Bertram Assignee: jaikiran pai When an MDB uses BMT a transaction is still begun when onMessage() is invoked. This is because org.jboss.as.ejb3.component.messagedriven.MessageDrivenComponent#isDeliveryTransacted doesn't check whether or not the MDB is using BMT. You can workaround this issue by using CMT with NOT_SUPPORTED.
