> catch (RecognitionException e) {
>       e.printStackTrace();
>       throw new ParseException(parser.errors);
>     }
> {code}
> Do not use {{e.printStackTrace()}} and print to STDERR.  Either remove or 
> replace with a debug-level log statement.  I would vote to simply remove.  
> There are several occurrences of this pattern in this class.
