Instead of, for example, a `dict`, or something else, as it could break the application at some point later, making it a security risk.

We also verify that we have a user with that username, and if not, we raise that same exception we created before.

Cet exemple peut sembler verbeux. Gardez à l'esprit que nous mélangeons sécurité, modèles de données, fonctions utilitaires et *chemins d'accès* dans le même fichier.

Mais voici le point clé.

La partie sécurité et injection de dépendances est écrite une seule fois.

   * Now, Finalizer no longer keeps an indirect strong reference to the static
   * FinalizableReferenceQueue field in ReferenceMap. The application class loader can be reclaimed
   * at which point the Finalizer thread will stop and its decoupled class loader can also be
   * reclaimed.
   *
   * If any of this fails along the way, we fall back to loading Finalizer directly in the
   * application class loader.
