Hi Sergey,
It looks like the instrumentation agent should handle mbeans that have
already been registered. It should catch the
InstanceAlreadyExistsException and continue. I'll open a JIRA. BTW,
the reason you start seeing the exception in 1.4 is because JMX is now
enabled by default. If you need to disable it, please follow the wiki
http://activemq.apache.org/camel/camel-jmx.html.
Thanks,
William
