Mario Fusco resolved DROOLS-546.
--------------------------------

    Fix Version/s: 6.1.0.Final
       Resolution: Done


We decided to not add a further exception but just prevent the NPE returning null when you try to get the value of a not existing field and ignoring the corresponding setter.

> factType.get(instance, "unknownField") is currently throwing an NPE. This gives improper information to the user/developper.
> I propose that it throws a new UnknownFactFieldException giving improved information giving good hints for debugging or enabling specific exception management.
> See pull request for test-case and proposed fix
