> I'm using the Hex codec to decode e.g. the string "qq". What surprises 
> me is that this obviously illegal hex value is decoded into one byte 
> value 255. In fact all non-hex 'character-pairs' are decoded to value 255.
> Wouldn't it be better to throw a DecoderException if illegal characters 
> are passed in?
> The current implementation decodes values that is is actually not able 
> to decode, which is wrong.
> Cheers,
