Au cours de la semaine dernière, j'ai eu des problèmes pour accéder à une application Web JBoss (v 4.2.2). Lorsque j'accède à la page d'accueil, j'obtiens une page d'erreur java.lang.NullPointerException. Après avoir consulté le journal de JBoss, il apparaît que trop de fichiers sont ouverts. Comment puis-je fermer ces fichiers ? Voici le résultat du journal JBoss :
