This happened ~20 times of 10,000 messages processed. As a result, the message has been lost.
The offending code in NotifyQueues.java (marked with >>> <<<):
Context context = NamingContext.getServerContext(environment);
Queue queue=null;
try
{
>>> queue = (Queue) context.lookup(destinationName); <<<
}
This context.lookup() returns null sometimes.
I was able to reproduce it only when the ESB listener's queue is served with >1 thread and the service was deployed on two nodes in the cluster (clustered JMS, ServiceInvoker used RoundRobin policy).
BEWARE! The context.lookup() is used on many different places without checking the return value != null.
