> 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
> Assignee: Joern Kottmann
> Fix For: 1.6.0
>
>
> In the Parser command-line tool, if an input line is comprised of solely
> whitespace, then you get an array index exception in parseLine
> String text = sb.substring(0, sb.length() - 1);
> 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.
