Thank you for the report Travis. Do you have a test case that triggers the

> In the last while loop in HelpFormatter.findWrapPos, it can pass
> text.length() to text.charAt(int), which throws a
> StringIndexOutOfBoundsException. The first expression in that while loop
> condition should use a <, not a <=.
