Description

When using the garbage collection feature of inactive queues, the queues are not collected if queue mirroring is turned on. The following snippet shows a basic configuration for reproducing the problem:

<broker xmlns="http://activemq.apache.org/schema/core"
          brokerName="localhost"
          dataDirectory="${activemq.base}/data"
          destroyApplicationContextOnStop="true"
          schedulePeriodForDestinationPurge="10000">

        <destinationInterceptors>
            <mirroredQueue copyMessage="true" postfix="" prefix="Monitor."/>
        </destinationInterceptors>

        <destinationPolicy>
            <policyMap>
                <policyEntries>
                    <!-- Set auto-cleanup of inactive topics and queues -->
                    <policyEntry queue=">" producerFlowControl="true" memoryLimit="50mb" gcInactiveDestinations="true" inactiveTimoutBeforeGC="30000">
                        <pendingQueuePolicy>
                            <vmQueueCursor/>
                        </pendingQueuePolicy>
                    </policyEntry>
                    <policyEntry topic=">" producerFlowControl="true" memoryLimit="50mb" gcInactiveDestinations="true" inactiveTimoutBeforeGC="30000">
                        <pendingSubscriberPolicy>
                            <vmCursor />
                        </pendingSubscriberPolicy>
                    </policyEntry>
                </policyEntries>
            </policyMap>
        </destinationPolicy>
</broker>

With this configuration, the topics will be collected, but the queues will not be collected. In order to get the queues to be collected, the <destinationInterceptors> section needs to be commented out.
