I am using the lastest 4.0 release build of ActiveMQ and I have been trying to produce messages in a JMS client and receive the messages in a STOMP client.
What I have found is that if the JMS Client adds header properties to the message to be delivered to ActiveMQ then when I subscribe with the STOMP client I am receiving the Error listed below. If I remove all header properties then the message is transmitted correctly. I have also found that if I send messages with a STOMP client that has header properties then everything works correctly. Any assistance would be greatly appreciated.
