J'ai besoin de vous s'il vous plaît. Que doit-je faire pour enlever cet erreur.

Déplace tes "close" dans un finally déjà, cela te permettra de fermer les ressources indépendamment des exceptions.

Ensuite, en survolant, je ne vois rien qui peut induire cette erreur hormis les "close", ce qui impliquerait que tu as une autre exception avant de fermer tes ressources.
