That should be "javax.servlet.jsp.HttpJspPage".

This is part of the spec, but I think we could still observe the spec and
not require a class to extend anything but HttpServlet.  The "implements
HttpJspPage", which is required by the spec, could be dynamically
generated.  You might try this on the reference implementation and see if
it's allowed.
