Description

When I execute

opennlp SentenceDetectorEvaluator -encoding UTF-8 -model pt.sentdetect.model -data pt.sentdetect.test

the result is

Usage: opennlp SentenceDetectorEvaluator -encoding charset -model model -data testData

I got the usage message although the right number of arguments. After short investigation I have found out that in the class SentenceDetectorEvaluatorTool, the validation for number of arguments is incorrect.

    if (args.length != 4) {
      System.out.println(getHelp());
      throw new TerminateToolException(1);
    }

Actually args.length is 6. Changing the condition to args.length < 6 solves the problem.
