> 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:
> {code:xml}
> <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>
> {code}
> 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.
