#58 unexpected behavior of Coreference

[Anonymous]

I want to use OpenNLP to do coreference, and I follow the example in the README file :

java opennlp.tools.lang.english.SentenceDetector \

opennlp.models/english/sentdetect/EnglishSD.bin.gz < text |

java opennlp.tools.lang.english.Tokenizer \

opennlp.models/english/tokenize/EnglishTok.bin.gz |

java -Xmx350m opennlp.tools.lang.english.TreebankParser -d \

opennlp.models/english/parser |

java -Xmx350m opennlp.tools.lang.english.NameFinder -parse \

opennlp.models/english/namefind/*.bin.gz |

java -Xmx200m -DWNSEARCHDIR=$WNSEARCHDIR \

opennlp.tools.lang.english.TreebankLinker opennlp.models/english/coref

But I got the wrong message:

Exception in thread "main" java.lang.NumberFormatException: For input string: "NUMBER_OF_VERB_FRAMES"

Moreover, I tried "NUMBER_OF_VERB_FRAMES" in Google, which shows this seems a problem somebody has already meet but I can not find the solution.
