----------------------------------

             Summary: Destination policy not applied when multiple policies with wildcard exist
                 Key: AMQ-8437
                 URL: https://issues.apache.org/jira/browse/AMQ-8437
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.16.3, 5.16.0
         Environment: centos 7; activeMQ version 5.16.3
            Reporter: Rohan Chauhan


I am setting up deadLetterPolicies for undelivered messages but the individualDeadLetterStrategy doesn't get applied if I use a wildcard. I was expecting creation of DLQ.app/events/foo to be created, for a queue named app/events/foo, and undelivered messages moved into it. Unfortunately the individual DLQ is not created and undelivered messages end up in default DLQ i.e. ActiveMQ.DLQ.


{code:java}
<destinationPolicy>
    <policyMap>
        <policyEntries>
            <!-- Set the following policy on all queues using the '>' wildcard -->
            <policyEntry queue=">">
                <!-- 
                        Tell the dead letter strategy not to process expired messages
                        so that they will just be discarded instead of being sent to
                        the DLQ, next we add specific policies for each queue. 
                        -->
                <deadLetterStrategy>
                    <sharedDeadLetterStrategy processExpired="false" />
                </deadLetterStrategy>
            </policyEntry>
            <policyEntry queue="app/events/*">
                <deadLetterStrategy>
                    <!--
                            Use the prefix 'DLQ.' for the destination name, and make
                            the DLQ a queue rather than a topic
                            -->
                    <individualDeadLetterStrategy queuePrefix="DLQ." useQueueForQueueMessages="true"/>
                </deadLetterStrategy>
            </policyEntry>
        </policyEntries>
    </policyMap>
</destinationPolicy>{code}
 

The individualDeadLetterStrategy works fine when I don't use wildcard.
