I put a post in the user forum for this, but thought I'd add something to this thread. I'm concerned about backward compatibility. I've got a test environment with all brokers at 4.0.1, except one I'm upgrading to 4.1. This would be how our production environment would be upgraded - a machine or so at a time.
However, the 4.0.1 brokers will not connect to the 4.1 broker, giving the following exception: Exception in thread "ActiveMQ Transport: tcp:///170.137.15.160:34695" java.lang.IllegalArgumentException: Invalid version: 2, could not l oad org.apache.activemq.openwire.v2.MarshallerFactory at org.apache.activemq.openwire.OpenWireFormat.setVersion(OpenWireFormat.java:329) at org.apache.activemq.openwire.OpenWireFormat.renegociatWireFormat(OpenWireFormat.java:569) at org.apache.activemq.transport.WireFormatNegotiator.onCommand(WireFormatNegotiator.java:100) at org.apache.activemq.transport.InactivityMonitor.onCommand(InactivityMonitor.java:122) at org.apache.activemq.transport.TransportSupport.doConsume(TransportSupport.java:87) at org.apache.activemq.transport.tcp.TcpTransport.run(TcpTransport.java:143) at java.lang.Thread.run(Thread.java:595) Caused by: java.lang.ClassNotFoundException: org.apache.activemq.openwire.v2.MarshallerFactory at org.apache.activemq.util.ClassLoading.loadClass(ClassLoading.java:104) at org.apache.activemq.openwire.OpenWireFormat.setVersion(OpenWireFormat.java:327) ... 6 more There must be an upgrade path for 4.1. If that means I have to go to 4.0.2 (which I did not try yet), that is OK. But, I can't possibly tell my management that I have to upgrade the AMQ version on all 50 or so machines we have in production.
