-----------------------------------

             Summary: Parser command-line tool exception on input line of solely whitespace.
                 Key: OPENNLP-650
                 URL: https://issues.apache.org/jira/browse/OPENNLP-650
             Project: OpenNLP
          Issue Type: Improvement
          Components: Parser
    Affects Versions: tools-1.5.3
            Reporter: Aaron Binns


In the Parser command-line tool, if an input line is comprised of solely whitespace, then you get an array index exception in {{parseLine}}
{code}
String text = sb.substring(0, sb.length() - 1);
{code}
because the whitespace doesn't produce any tokens thus sb.length() is 0, and you wind up with an end position of -1.

Simple solution is to .trim() the input string in ParserTool.
