> While registering a resource change listener, we encountered the following exception :

> On further debugging, we found that issues lies in this snippet :
> {code:java}
> if (exclude.equals(include) || isAncestor(exclude, include)) {
> includesRemoved.add(include);{code}
> 'exclude' can be null if the getOakPath() method returns a null. This NPE causes listeners(ResourceChangeListener in our case) to fail at registration.
