Symfony cached route files:

appDevUrlMatcher.php appDevUrlGenerator.php

in your cache dir, var/cache/dev(prod)

just delete these files

 protected function warmUpRouteCache() {

    $router = $this->get('router');
    $filesystem = $this->get('filesystem');
    $kernel = $this->get('kernel');
    $cacheDir = $kernel->getCacheDir();

    foreach (array('matcher_cache_class', 'generator_cache_class') as $option) {
        $className = $router->getOption($option);
        $cacheFile = $cacheDir . DIRECTORY_SEPARATOR . $className . '.php';
        $filesystem->remove($cacheFile);
    }

    $router->warmUp($cacheDir);
}

it works for me.
