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.

New subject: [JBoss JIRA] Commented: (JBESB-1484) context.lookup() can return null
[ http://jira.jboss.com/jira/browse/JBESB-1484?page=comments#action_12395193 ]
Kevin Conner commented on JBESB-1484:
-------------------------------------
context.lookup does not return null and needs no checking.
The problem appears to lie with the implementation of NamingContext.getServerContext which
has the following issues.
- It generates a key based on HashTable which is flawed (order is indeterministic)
- It does not guarantee thread safety for contexts
- It can return null in certain failure scenarios.
context.lookup() can return null

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);

This context.lookup() returns null sometimes.
I was able to reproduce it only when the ESB listener's queue is served with >1

ServiceInvoker used RoundRobin policy).
BEWARE! The context.lookup() is used on many different places without checking the return

This happened ~20 times of 10,000 messages processed. As a result, the message has been

The offending code in NotifyQueues.java (marked with >>> <<<):
Context context = NamingContext.getServerContext(environment);
Queue queue=null;
try

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.

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

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.
