8.2.x

Description: 

Drupal\Core\Routing\Access\AccessInterface is deprecated since 8.2.x and should not be used anymore.

Routing access check classes do not implement it anymore so any comparisons if an object is an instance of AccessInterface will return FALSE.

Also make sure that you do not use AccessInterface in any method type hints.
