I have the same problem.  The CPU is maxed out.

Launch through Spring (with org.apache.activemq.xbean.BrokerFactoryBean) and CPU is 100%
Launch same config through command line (./bin/activemq xbean:../conf/my-activemq.xml) and CPU is fine (very low)

I've tried this and received the same results for both AMQ 4.1.1 and 5.0-SNAPSHOT.
I've also tried both Spring 1.2.8 and Spring 2.0 with these configs:

--------- Spring 1.2.8 ------------
<bean id="brokerFactory" class="org.apache.activemq.xbean.BrokerFactoryBean">
                <property name="config" value="classpath:/my-activemq.xml" />
                <property name="start" value="true" />
        </bean>

-------- Spring 2.0 --------------
 <amq:broker brokerName="brokerFactory" useJmx="true" persistent="false">
        <amq:managementContext >
    <amq:managementContext connectorPort="1099" jmxDomainName="org.apache.activemq"/>
    </amq:managementContext>
...
  </amq:broker>

I'm not sure how to read this issue, but does this (https://issues.apache.org/activemq/browse/AMQ-1090) mean that since this 100% issue was reported in 2006, it's not a priority fix until release 5.2.0?  Any temporary fixes for this?
