> When {{PooledConnectionFactory}} is used with Failover transport, insufficient access
control settings on the broker result in an excessive number of consumer objects on the broker
once the access control settings are properly set. 
> Here is an example Spring XML configuration:
> {code:xml}
> <beans ...>
>   <bean id="jmsConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
>     <property name="brokerURL" value="failover:(tcp://localhost:61616)" />
>     <property name="userName" value="test" />
>     <property name="password" value="test" />
>   </bean>
>   <bean id="pooledConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory">
>     <property name="connectionFactory" ref="jmsConnectionFactory" />
>     <property name="maxConnections" value="10" />
>   </bean>
>   <bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
>     <property name="connectionFactory" ref="pooledConnectionFactory" />
>     <property name="destinationName" value="TEST" />
>     <property name="messageListener" ref="messageListener" />
>     <property name="concurrentConsumers" value="10" />
>   </bean>
>   <bean id="messageListener" class="com.redhat.issues.amq.SpringJmsConsumer" />
> </beans>
> {code}
> In this configuration we expect only one connection and 10 consumers for {{TEST}} queue,
but after following the reproducer steps we see around 10 connections and 100 consumers for
the queue on hawtio. In the above configuration Spring DMLC is used but we can reproduce the
issue without Spring.
