TokenNameFinderCrossValidator hangs when passed a NameEvaluationErrorListener...

TokenNameFinderCrossValidator works fine if passed null or any other listener except a "NameEvaluationErrorListener", for the l"listeners" parameter (last vararglist parameter in the constructor)...I have tested it with DetailedFMeasureListener and null and it works fine. When trying to pass an array with the 2 listeners i want (DetailedFMeasureListener, NameEvaluationErrorListener) it just hangs after the processing the last partition of data, rather than showing the F-score! It is not a show stopper because i can simply pass null and get my F-score, but it would be nice if could see the misclassifications as well...
