This is a bug in ErrorDispatcherValve that occurs if
the request doesn't map to a context, i.e. line 280
is:
ErrorPage errorPage = context.findErrorPage(statusCode);
and context is null. This bug has been fixed and appears
in the current Tomcat 4.0-dev and will appear in the next
4.1 and 4.0.2 releases.
Cheers,
Larry
