Description Matthias Wienand

The AbstractFXInteractionPolicy provides two methods that can be used to determine if a policy is responsible for processing a given EventTarget. These methods need to be guarded against the host part being removed from the visual-part-hierarchy or from the viewer, respectively.

I added null-checks for the root-part and the viewer to these methods. The code is published on the master branch, therefore, I resolve this ticket as fixed for 4.0.0 RC2.
