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

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

OK problem solved...

I'm terribly embarrassed to say that this is not an openNLP issue but a 
Clojure issue! In fact, not even a Clojure issue - it is a leiningen 
issue! it turns out that if i use "trampoline" to run my code in a 
separate VM instead of nesting it inside leiningen's, output from 
System.err is redirected appropriately to my terminal and everything 
shoes as expected... I was right to think that it had somethign to do 
with sdtin and sdtout!!! I do apologise for any time wasted on this... I 
will close the issue immediately...

Jim

p.s: William i owe you a beer...next time you're in Manchester drop me 
an email...(not joking :-) )

> 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...
