Due to PHP Bug #53727, is_subclass_of might return inconsistent results on some PHP versions if \IrishDan\NotificationBundle\Adapter\MessageAdapterInterface::class can be an interface. If so, you could instead use ReflectionClass::implementsInterface.

            }

            $subscriberDefinition->addMethodCall('addAdapter', [$id, new Reference($id)]);
