JMS objects are shared between consumers in JBossMessaging

Issue

• The code in our application has a clustered JMS queue where the only type of message being sent is a StreamMessage with a single long value in its payload, created roughly as follows:

        StreamMessage msg = queueSession.createStreamMessage();
        msg.writeLong(somevalue);
        queueSender.send(msg);

• The MDB that receives on the queue does this in its onMessage(Message msg) method:

  long myvalue = ((StreamMessage)msg).readLong();
  

It works most of the time. But once in awhile (about 5%) a MessageEOFException is thrown out of readLong:

javax.jms.MessageEOFException:
        at org.jboss.jms.message.JBossStreamMessage.readLong(JBossStreamMessage.java:356)
        at org.jboss.jms.message.StreamMessageProxy.readLong(StreamMessageProxy.java:112)
        at aaa.bbb.ProcessExitProcessorBean.onMessage(ProcessExitProcessorBean.java:236)
        ...
