Thanks Christopher.This is the custom exception.All that our code
attempts is to invoke the
servletRequest.setAttribute where servletRequest is a HttpServletRequest
and it is not cached.
When you say "
This smacks of a cached request
object, which is totally illegal.
" what do you mean by that?

The value of context is null.Has anybody faced this issue?This doesn't
happen all the time.
Where is the rest of the stack trace? This smacks of a cached request
object, which is totally illegal.
