> Currently the code in org.apache.commons.cli.OptionValidator generates an IllegalArgumentException which contains the message:-
> "illegal option value '" + ch + "'"
> This is generated in two places, one for single character options and one for multi character options.
> However this does not tell the caller which option it is contains this 
> character, which makes debugging the error without the source (i.e most users) extremely difficult.
> Would it not be possible to change the message to:-
> "illegal option '" + opt + "' value '" + ch + "'"
> which would then at least identify the offending option.
