> {code}
> This is not informative, by checking the code in JobTool class:

>     // Now feed the arguments into the tool itself.
>     try {
>       childOptions = childTool.parseArguments(parseableChildArgv,
>           null, childOptions, false);

>       System.err.println(e.getMessage());
>       return 1;
>     }
> {code}
> The ParseException pe's message has been dropped, we should print out the message in
the exception so that more meaningful message will be printed.
