Subject [jira] Resolved: (CAMEL-1718) Make management independent of impl
Date Thu, 12 Nov 2009 20:07:52 GMT


Claus Ibsen resolved CAMEL-1718.

    Resolution: Won't Fix

I am resolving this as wont fix.

The codebase in 2.1 has changed since 2.0.
So after the 2.1 release feel free to take a look at it again.

> 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.
