Carsten Ziegeler commented on SLING-3457:
-----------------------------------------

I'm not sure if we should do this. If the method returns "true" I would expext 
that the resource is a NonExistingResource and therefore then call any method 
on the resource object which then results in an NPE.
Even the same if the method would return "false", so I think a NPE is the best 
option here. at some point the client code has to check whether the resource is 
null or not

> Change ResourceUtil.isNonExistingResource(null) to return true instead of NPE.
