title: Format ParseException with JavaCC
body: <p>I was wondering how could it be possible to format in a human-readable format a ParseException thrown by JavaCC: in fact it includes fields such as<code>beginLine</code>, <code>beginColumn</code>, <code>endColumn</code>, <code>endLine</code> in the token reference of the exception, but not the reference to the source parsed.</p>
  
  <p>Thanks! :)</p>
