Not related to the latest messaging upgrade, but we are seeing tons of failures on o.j.test.jbossmessaging: http://hudson.qa.jboss.com/hudson/view/JBoss%20AS/job/JBoss-AS-5.0.x-Test... Something is not deploying properly: http://hudson.qa.jboss.com/hudson/view/JBoss%20AS/job/JBoss-AS-5.0.x-Test... ... Caused by: org.jboss.deployment.DeploymentException: Trying to install an already registered mbean: jboss.messaging.destination:service=Topic,name=testJoramTopic at org.jboss.system.ServiceCreator.install(ServiceCreator.java:88) at org.jboss.system.ServiceCreator.install(ServiceCreator.java:362) Was something changed with how we handle duplicate registations?
