Hmmmm, that's interesting. I wonder if the getCookies implementation
is perhaps catching those exceptions. What servlet engine are you
using, you never said? (And how are you going to be able to use your
own getCookies, since it's part of the servlet engine's
HttpServletRequest implementation?)
A couple of comments:
1. You might pass this info on to the servlet engine vendor, it might
be indicative of a problem in it (and/or perhaps the JSDK still has
a problem)
2. You might think about not using cookies which have an '=' (or any
of the other restricted characters) in their value. This might
cause some pain in the short run, but may be easier in the long
run.
