Dan Florian resolved DNA-568.
-----------------------------

    Resolution: Done


Changed the following classes so that they return false when a null observable is passed in to the register method:

org.jboss.dna.repository.RepositoryLibrary
org.jboss.dna.graph.observe.MockObservable
org.jboss.dna.graph.observe.ObservationBus
org.jboss.dna.jcr.JcrRepository#RepositoryObservationManager

> The Observable.register(Observable) method allows a null observable. When it is null the method should return false. These classes are violating that contract:
> org.jboss.dna.repository.RepositoryLibrary
> org.jboss.dna.graph.observe.ObservationBus
> org.jboss.dna.jcr.JcrRepository#RepositoryObservationManager
