Looks like a dependency issue to me. Look at the location of this message: [url] [testng] DEBUG [org.jboss.jms.server.destination.TopicService] Creating jboss.mq.destination:service=Topic,name=testTopic [/url] compared to when the lookup occurs. The resource adapter will try to activate the MDB again 10 seconds after the failure: "reconnect=10" in the activation config.
