> MatchesEvaluator, line 56 - When the flow file attributes do not contain the attribute specified in the comparison portion of a 'matches' operation, the Pattern.compile(null) throws an NPE.
> Since there is no guarantee that a specified flow file attribute is present, this should simply return BooleanQueryResult(false) if the desired attribute does not exist.
