Using ActiveMQ 5.11.0 with this setting

  <bean id="pooledConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" init-method="start" destroy-method="stop">
    <property name="maxConnections" value="8" />
    <property name="connectionFactory" ref="jmsConnectionFactory" />
    <property name="useAnonymousProducers" value="false"/>
  </bean>

As useAnonymousProducers=false, then I do not have that in the tree, but the MBeans gets created + destroyed and it does the same round robin fashion with my 8 connections.
