Stomp Connection Dispatcher Fails on NPE

Rate this Message:
We have been using ActiveMQ 5.2 on Windows for about 6months with a relatively low message throughput (a maximum usage 1 message every 4 seconds, nothing crazy) and it was working perfectly. We have several clients that connect through either an OpenWire or Stomp connection and communicate through Queues.
Several days ago I started testing higher throughput (several messages/second) messaging by publishing to a Queue from an OpenWire connection and consuming the message on a Stomp connection. At some point there is a failure in the Dispatcher for the Stomp connection and my client stops receiving messages. The OpenWire connection is unaffected and continues filling the Queue. I have since upgraded to ActiveMQ 5.3 because there were some issues fixed related to Stomp connection, but still see the same issue. The only exception that is displayed in the log is at the bottom of this post. I'm going to continue to look for a test case to reproduce my error, but in the mean time thought I would poll the experts for some advice. Thanks, Ben Exception in thread "ActiveMQ Connection Dispatcher: /127.0.0.1:3047" java.lang.NullPointerException at org.apache.activemq.transport.stomp.LegacyFrameTranslator.convertMessage(LegacyFrameTranslator.java:69) at org.apache.activemq.transport.stomp.ProtocolConverter.convertMessage(ProtocolConverter.java:594) at org.apache.activemq.transport.stomp.StompSubscription.onMessageDispatch(StompSubscription.java:92) at org.apache.activemq.transport.stomp.ProtocolConverter.onActiveMQCommand(ProtocolConverter.java:576) at org.apache.activemq.transport.stomp.StompTransportFilter.oneway(StompTransportFilter.java:56) at org.apache.activemq.transport.MutexTransport.oneway(MutexTransport.java:40) at org.apache.activemq.broker.TransportConnection.dispatch(TransportConnection.java:1190) at org.apache.activemq.broker.TransportConnection.processDispatch(TransportConnection.java:779) at org.apache.activemq.broker.TransportConnection.iterate(TransportConnection.java:815) at org.apache.activemq.thread.DedicatedTaskRunner.runTask(DedicatedTaskRunner.java:98) at org.apache.activemq.thread.DedicatedTaskRunner$1.run(DedicatedTaskRunner.java:36) Edit : I thought I would also note that with the nice new "Connector" page on the admin interface it shows the connection to my Stomp client as connected, and similarly the "Queues" page lists the Stomp consumer on the Queue, but the pending messages just keeps growing. |

Hi,
can you open a jira for this, so it doesn't get lost? It would be great if you could create a reproducible test case as well.
