Subject [jira] [Commented] (OPENNLP-466) TokenNameFinderCrossValidator hangs when passed a NameEvaluationErrorListener...

Jim Piliouras commented on OPENNLP-466:
---------------------------------------

Ok i see...thanks for trying anyway

I'm starting to get increasingly suspicious about the 
NameEvaluationErrorListener's default constructor
which accepts the error stream for output (System.err)...the way the 
program hangs is just plain weird...one could say that it doesn't 
"display stuff" rather than "hangs"...of course the argument then is 
that the method would at least return something... of the top of my head 
i can try passing System.out instead of System.err and see what happens...

Should i close the issue and reopen in case i find something else?

Jim

> 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...
