> Executing a Filter implemented by the Felix Framework FilterImpl class is not thread safe, as the Filter.Implmatch() methods are not synchronized but use a Mapper and Evaluator instance fields which are modified while matching the filter.
> Two options seem to exist:
>    1. Make the match() methods synchronized
>    2. Create Mapper and Evaluator instances on each match() call
> My assumption is that the second method tends to be better because of the synchronization needed with the first approach.
