From the code (and stack-trace), the problem is with an unescaped '%'
sign
in the query-string. Something like: /foo.jsp?progress=58%foo=bar
or
/foo.jsp?value=%xy.

Dude -- I got the exact same thing yesterday and posted it! ;) Still

Howdy,
User agents aren't 100% reliable and I think I remember something about

Howdy,
couldn't you set up an error-page that only runs for this exception and
then
print out the parameters from that page? Or does the request not get

My wild guess is that there could be a mismatch between the request
