I seem to be having a similar problem. This code works fine with the
count set to something less than 100. At about 100 (with a content
length of around 1200) the HttpServletRequest doesn't have any of the
parameters.
Invoke with /servlet/xxx?count=nnn, play with the nnn and at some point
you'll see the "it's whacked" message.
(Sorry 'bout the formatting.)
