Hello, I'm currently running a 4.0.1 server with 4.0.1 clients. I'd like to upgrade everything to 5.1.0, but not at the same time. Ideally, I'd do a 2 stage upgrade where I first bump the server to 5.1.0 and then the clients.
Are there any known compatibility issue between a 4.0.1 client and a 5.1.0 server? I ask because in my testing there appears to be some problems. I'm running 4.0.1 clients against a 5.1.0 server and see errors similar to the following in the servers log over and over and eventually run out of heap. ERROR Service - Async error occurred: java.lang.NullPointerException java.lang.NullPointerException at org.apache.activemq.command.SessionId.<init>(SessionId.java:39) at org.apache.activemq.command.SessionInfo.<init>(SessionInfo.java:37) at org.apache.activemq.state.ConnectionState.<init>(ConnectionState.java:47) at org.apache.activemq.broker.TransportConnectionState.<init>(TransportConnectionState.java:35) at org.apache.activemq.broker.TransportConnection.processAddConnection(TransportConnection.java:619) at org.apache.activemq.command.ConnectionInfo.visit(ConnectionInfo.java:125) at org.apache.activemq.broker.TransportConnection.service(TransportConnection.java:292) at org.apache.activemq.broker.TransportConnection$1.onCommand(TransportConnection.java:180) at org.apache.activemq.transport.TransportFilter.onCommand(TransportFilter.java:68) at org.apache.activemq.transport.WireFormatNegotiator.onCommand(WireFormatNegotiator.java:143) at org.apache.activemq.transport.InactivityMonitor.onCommand(InactivityMonitor.java:206) at org.apache.activemq.transport.TransportSupport.doConsume(TransportSupport.java:84) at org.apache.activemq.transport.tcp.TcpTransport.doRun(TcpTransport.java:196) at org.apache.activemq.transport.tcp.TcpTransport.run(TcpTransport.java:183) at java.lang.Thread.run(Unknown Source) Does anyone have any input on this? Is there a recommended upgrade path or a client/server compatibility matrix floating around?
