Subject class org.apache.camel.management.mbean.ManagedService is not a JMX compliant MXBean
Date Fri, 26 Jun 2015 19:39:13 GMT
Good day -

I am trying to port a production server's test suite to use ActiveMQ
(5.7.0.fuse-71-047) ,  where the
production server normally uses a licensed copy of SwiftMQ-HA ,  with 
apache-camel-2.9.0.fuse-7-061 and  
Spring Framework ( 3.1.2-RELEASE ) - us developers do not get access to
SwiftMQ-HA licenses.  
These versions cannot be changed easily .

Previously the test suite used to fake sending JMS messages with a mock, but
this is
now no longer possible - it must receive real JMS messages and send them. 
  
I have got the server to include the camel-amqp jar and dependencies in its
classpath ,
and modified its Camel configuration to use 'amqp:' prefixed URIs instead of
'swiftmq:'
preifixed URIs - that is the only change I've made to the Camel
configuration.

Now I am getting this exception during Spring initialization, but because it
is caught, 
Spring initialization never terminates - ie. the call to
'ClassPathXmlApplicationContext("myAppContext.xml")
never returns - the complete exception text is:

"javax.management.NotCompliantMBeanException: MBean class
org.apache.camel.management.mbean.ManagedService does not implement
DynamicMBean, neither follows the Standard MBean conventions
(javax.management.NotCompliantMBeanException: Class
org.apache.camel.management.mbean.ManagedService is not a JMX compliant
Standard MBean) nor the MXBean conventions
(javax.management.NotCompliantMBeanException:
org.apache.camel.management.mbean.ManagedService: Class
org.apache.camel.management.mbean.ManagedService is not a JMX compliant
MXBean).
"

The main thread is stuck in this stack frame and never leaves it :

It is obviously trying to register the management agent , but this gets the 
indicated exception, which is caught, and
the process is repeated ad infinitum.

As the thread is entirely within Spring + Camel code I'm a bit stumped as to
what to do about this .

Any ideas about how to workaround this problem with current Spring, Camel
and ActiveMQ versions given above would be 
much appreciated .

Why isn't the org.apache.camel.management.mbean.ManagedService  a JMX
compliant MXBean ?

Any responses gratefully received.

Thanks & Regards,
Jason
