Configuring Embedded Broker with Spring/JBoss JMX issues

Spring 2.5.1
ActiveMQ 5.1.0
JBoss 4.2.1

I can not get the embedded broker configured using Spring context
configuration.  I've tried pretty much every permutation and parameter for
the broker but the result is always the same.  I am beginning to think there
is an issue with the way activemq registers its mbeans with the JBoss MBean
server.  I saw this in activemq 4.1.0 as well which is why I upgraded to
5.1.0.  But I still get the same result.  Any help is much appreciated, I've
been stuck on this for a couple of months.

Spring application context...

    <amq:broker start="true" brokerName="localhost" persistent="false"
useJmx="true">
        <amq:managementContext>
            <amq:managementContext createConnector="false" />
        </amq:managementContext>
    </amq:broker>

    <!-- JMS ConnectionFactory to use, configuring the embedded broker using
XML -->
    <amq:connectionFactory id="jmsFactory" brokerURL="vm://localhost">
    </amq:connectionFactory>

Starting JBoss I get (Note: Spring context is intiatilzed via a jboss
startup MBean)...

Use of the BrokerFactoryBean is also very easy with the activemq.xml:

BrokerFactoryBean brokerFactory = new BrokerFactoryBean(new
ClassPathResource("path/to/activemq.xml"));
brokerFactory.afterPropertiesSet();
BrokerService broker = brokerFactory.getBroker();
