      1) start the broker with the activemq.xml attached
      important configuration in attached activemq.xml

      • runtimeConfigurationPlugin is configured
      • compositeQueue is configured

      2) produce a message to the composite queue - just to ensure everything is instantiated.

      3) uncomment the following destination policy entry and save
      <!--policyEntry topic="YYY.>" producerFlowControl="true">
      </policyEntry-->

      RESULT:
      Once the runtimeConfigurationPlugin recognises the configuration has been updated,
      it will generate the ClassCast exception in the brokers logs at ERROR log level.

      Configuration has defined the following composite queue: 

      <destinationInterceptors>
          <virtualDestinationInterceptor>
            <virtualDestinations>
              <compositeQueue name="my.composite.queue">
                <forwardTo>
                  <filteredDestination selector="header = 'one'" queue="my.filtered.destination"/>
                  <topic physicalName="my.topic" />
                </forwardTo>
              </compositeQueue>
            </virtualDestinations>
          </virtualDestinationInterceptor>
        </destinationInterceptors>

      When a new destination policy is set

        <policyEntry topic="YYY.>" producerFlowControl="true">
              </policyEntry>

      The following ERROR is thrown in the logs
