new \SixtyEightPublishers\User\DoctrineIdentity\Event\IdentityNotFoundEvent($identityReference, empty($namespace) ?

It seems like $identity can also be of type object<Nette\Security\IIdentity>. However, the property $currentIdentity is declared as type object<Nette\Security\Identity>|null|boolean. Maybe add an additional type check?
