https://github.com/apache/wicket/blob/wicket-6.17.0/wicket-request/src/main/java/org/apache/wicket/request/http/handler/RedirectRequestHandler.java#L99 says that getRedirectUrl() returns null. So something calls RedirectRequestHandler's constructor with null url. Wicket doesn't instantiate this class for its needs, so it should be your application.
