<broker xmlns="http://activemq.apache.org/schema/core"; useJmx="true"
persistent="false">
<!-- Use the following to configure how ActiveMQ is exposed in JMX

I also commented SUNJMX in activemq-admin.
This configuration gives me the exception -
2008-08-18 15:32:12,739 DEBUG ManagementContext - Failed to

When I change & comment entire managementContext in activemq.xml & uncomment
SUNJMX, things work fine. I don't get the exception.
