William Tam updated CAMEL-606:
------------------------------

    Attachment: patch.txt

I will update wiki once this patch has been applied.

* By default, Camel mbean objects are registered with a mbean server and performance counters are enabled. However, RMI connector server is not started by default.
* Mbean server is "found" by mbean server's default domain name as it can be shared among camel contexts and with other application when it is desirable (as mentioned in CAMEL-613).
* If no mbean server can be found, a new one will be created.  
* As before, it is also possible to use the platform mbean server.
* System properties (found in JmxSystemPropertyKeys.java) and Spring configuration (found in CamelJMXAgentType.java) support the same set of configuration parameters.
* Instrumentation agent can be disabled by system property or spring configuration.
* Default Instrumentation agent is started and stop by the camel context as a service eliminating the need for SpringInstrumentationAgent subclass.
* Moved CamelChoiceWithManagementTest from spring to core where it belongs 
* updated RouteBuilderTest, ErrorHandlerTest to account for instrumentation interceptors
* Fixed some of the JMX tests that does not clear and restore system properties properly and release mbean servers at the end of the test.
* Update AggregatorType to allow it to be wrapped by interceptors.
* add ErrorHandlerWrappingStrategy mechanism as we need to prevent instrumentation interceptor from being wrapped by ErrorHandlers.
* rename LifecycleStrategy.onContextAdd() to onContextStart() since the lifecycle strategy is typically created after camel context.  Therefore, we are not really able to invoke the lifecycle strategy at that time.  It's more meaningful to be notified when camel context is started instead.
* since the default domain name for the mbean server and the domain name of the registered mbean object can be differ, we make them into different properties.  
* Add a check in ProcessorType.wrapProcessorInInterceptors() to prevent intercept ref from changing target processor.  It is a potential cycling problem.  This problem is discovered by enabling instrumentaton interceptor in StreamCachingInterceptorTest.  We'll probably should revisit StreamCachingInterceptor.  I'll create a JIRA.
* workaround NPE (CAMEL-620) in ResequencerType to allow createProcesssor to be invoked (so we can wrap Resequencer by an interceptor).
*  add async support for InstrumentationProcessor
* Fix CAMEL-553 (Firewall-friendly JMX Connector URL) by adding a property for RMI connection port.

> > Should we consider enabling JMX as default in Camel? It runs on JDK1.5 and thus its possible.
> Yeah, I think we should.
> > What is the default in ServiceMix? Maybe Camel should align what they do?
> AFAIK ServiceMix and ActiveMQ default it to true. Folk should have to disable it IMHO as its so useful
