AbstractHandlerExceptionResolverModelAndView that represents a specific error page if appropriate.
May be overridden in subclasses, in order to apply specific exception checks. Note that this template method will be invoked after checking whether this resolved applies ("mappedHandlers" etc), so an implementation may simply proceed with its actual exception handling.
