> Currently management and impl are tangled by a InstrumentationLifecycleStrategy and DefaultCamelContext. For example the DefaultCamelContext decides if JMX should be used and falls back to the DefaultLifecycleStrategy. 
> I think DefaultCamelContext should not know about JMX. So my proposal is to add a fallback lifecycle strategy to IntrumentationLifecycle. So it can delegate to this strategy if jmx does not work. So this logic can be removed from DefaultCamelContext.
> Another issue is with Service and ServiceSupport. ManagedService refrences ServiceSupport instead of Service. I think this is only because it needs an isStarted method. So I suggest to add this method to Service. Of course this means that several classes that implement Service need one new method but I think this is ok as isStarted can be quite usefull anyway.
> Additionally I would move ServiceSupport to camel as many packages need it. 
> Together these changes make the dependencies much easier to understand and remove cycles.
> I will add a patch for this shortly and hope it can be included into 2.0 as it changes the API.
