             Summary: Cellar cluster event handler should check the local 
status before performing an operation
                 Key: KARAF-2205
                 URL: https://issues.apache.org/jira/browse/KARAF-2205
             Project: Karaf
          Issue Type: Improvement
          Components: cellar-core
            Reporter: Jean-Baptiste Onofré
            Assignee: Jean-Baptiste Onofré
             Fix For: cellar-3.0.0, cellar-2.3.0


When a cluster event is broadcasted to the different event handlers, those 
cluster even handlers should check the local status of the resource before 
updating it.

For instance, it means that the BundleEventHandler should check the if a bundle 
is not already started before starting it.

Else, it means that we may have some infinite loops: the event handler 
"directly" updates the local resource, the local resource listener get the 
local change, and brodcasts a cluster event.
