Description

If you have a 404 specified in your web.xml that points to some wicket page, and that page throws a RestartResponseAtInterceptPage exception, you end up with a NullPointerException when trying to create the URL for the page. The NPE is because forwardUrl is not null, but filterPath is (in ServletWebRequest#getRelativePathPrefixToWicketHandler())

See the attached quickstart and go to http://localhost:8080/app-context-path/mounted-pattern/akdslfjasdklfj (which doesn't exist) to see the issue.
