  } finally {
    if ($container_id !== spl_object_id(\Drupal::getContainer())) {
      // When rebuilding the container,
      // \Drupal\Core\DrupalKernel::initializeContainer() saves the hashes of
      // the old container and passes them to the new one. So __sleep() will
      // recognize the old services and then __wakeup() will restore them from
      // the new container.
