IllegalArgumentException Exception in URLDecoder

Hi Guys,

I'm running into a exception...

Basically... when I submit any text containing the symbol '%', it falls
over.
E.g. 
req.getQueryString() is: p_comments=Test+%25

Which is "Test %"

I've traced it to the HttpServletRequestWrapper class, line 398.

Which says, 
queryString = java.net.URLDecoder.decode(queryString);

I think the decode function is attempting to 'decode' the string a second
time..

Help?
Regards
KD
