On this bug, when you have a MessageSubscriber, when the message is transfered over the Cluster, sometimes you get instances of Topic. (condition replicated on DistributedTest::testDestinationTypeOnMessage, which is just Phillip's test converted as a testcase) Looking at MessageCustomer, it aways create producers and consumers as Queues. To fix that I'm doing these changes: I - Exposing the isQueue attribute on the Condition interface II - MessageSucker will now receive the condition as well (besides just the Queue) III - MessageSucker will create a Topic or Queue according to the condition. | - JBossDestination dest = new JBossQueue(localQueue.getName(), true); | + JBossDestination dest = condition.isQueue()?new JBossQueue(localQueue.getName(), true): new JBossTopic(localQueue.getName(), true); | producer = localSession.createProducerDelegate(dest); Anyone sees any problem on the fix as described?
