<p>You are probably using different versions of ActiveMQ jars on the client and the broker. Try using the same jars on each node and the problem should go away.</p>

<p>Once 4.0 is GA we will be freezing the wire format version then increasing it for every future GA release - so the error message you get going forward should be more explicit</p></div>
