Hi, >From what I see, the FilterImpl.match() methods are not synchronized yet a single instance for the Mapper and Evaluator. I think, either the match() methods should synchronize or the Mapper and Evaluator instances should be created for each call to match.
I assume, the second solution (creating new instances on each call) would probably be better as synchronization overhead tends to be more heavy weight than memory allocation.
