protected function lazyLoadCache() {
    parent::lazyLoadCache();
    // On a cold start $this->storage will be empty and the whitelist will
    // need to be rebuilt from scratch. The whitelist is initialized from the
    // list of all valid path roots stored in the 'router.path_roots' state,
    // with values initialized to NULL. During the request, each path requested
    // that matches one of these keys will be looked up and the array value set
    // to either TRUE or FALSE. This ensures that paths which do not exist in
    // the router are not looked up, and that paths that do exist in the router
    // are only looked up once.
