ActiveMQ has already fixed it, according to http://issues.apache.org/activemq/browse/AMQ-1232 I think I was misunderstood - I think we shouldn't do any checks on the value passed to setJMSDestination - neither in setJMSDestination, nor in ProducerAspect. It's simply not necessary (as far as I can tell), the spec even says we must ignore the value completely. My question was whether we should also skip all checks on JMSReplyTo - e.g. to allow sending a JBossMessage with JMSReplyTo set to an ActiveMQ destination.
