             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.2.0, 5.0.0, 4.1.0
         Environment: Windows XP Profesional - 32 Bit.
JDK 1.5 Update 8 
Broker Running in Jboss

I am facing a problem on receiving messages by multiple blocked receivers from 
a single Queue with different correlation id.

Here is what exactly I am doing.

My client thread is publishing a message ( having a unique co-relationid) to a 
RequestQueue and waiting for a response (blocked)
on Response Queue with the same co-relationid.  I have such 100 client threads.

The client thread is publishing a message using normal JMS (w/o Spring) whereas 
receiving the response using Spring JMSTemplate
using object=jmsQueueTemplate.receiveSelectedAndConvert(destinationName, 
"JMSCorrelationID='" + correlationID+ "';

the other side, Spring Message POJOs are consuming the published message from 
RequestQueue, processing it and sending back the response to ResponseQueue with 
the co-relation id set using normal publishing (w/o Spring).


My Observations

I have sent 1000 unique co-relationId messages (using 100 client threads) but 
received 992 unique co-related id messages;
8 duplicated co-related id messages and dropped 8 unique co-related id messages.

This is happening under 100 client threads load using Jmeter
