             Summary: Clarify and complete removal resource events
                 Key: SLING-6066
             Project: Sling
          Issue Type: Sub-task
          Components: API, JCR, ResourceResolver
            Reporter: Carsten Ziegeler

As recently discussed in the mailing list, if a ResourceChangeListener is 
interested in removal events, the listener might not get the event it is 
interested in. For example, if the listener is registered with a glob pattern, 
like **.jsp, but the parent (or any parent) of a jsp is removed. In that case 
no removal event for the jsp itself is sent.  Which means the listener is 
unaware of removals.

We need to clarify this in the javadocs, but also should implement handling 
removal in the following:
If a listener is registered for removal events - regardless if a glob pattern 
is used or not - the listener will be notified of removals of any parent node 
up to the top level node. For example if a listener is interested in 
/a/b/c/**/*.jsp, a removal of any resource below "c", but also removal of "a", 
"b", or "c" is reported to the listener.
