Java erreur fatale, ne sait pas ce que cela signifie

2010-03-22 5 views

Il arrive au même endroit dans mon code (mais pas la première fois que la méthode est exécutée), mais je ne peux pas faire la tête ou la queue de ce qui ne va pas. (Doublement comme c'est le code pour un robot).Java erreur fatale, ne sait pas ce que cela signifie

Soyez le plus reconnaissant si quelqu'un peut me donner une idée du genre de problème. Je suppose que c'est à voir avec le threading (application multi-thread) mais je ne sais pas vraiment quoi?!? Inquiet comme date limite pour uni projet est imminente !!!

Avez-vous le code source? Cela aiderait à le voir. – ponzao

Merci pour les réponses, le gestionnaire de paquets d'ubuntu n'avait pas de mise à jour pour le jre mais j'ai mis à jour d'autres parties et cela fonctionne maintenant. Impossible de fournir le code source malheureusement, un projet uni donc je serais paranoïaque sur le plagiat etc. –

"mais j'ai mis à jour d'autres parties" - quelles parties? J'ai des problèmes similaires sur debian (squeeze/sid) et je pense que c'est un bug JVM car l'exception se produit dans le thread GC, mais j'ai essayé 1.6_14 à 1.6_18 et tous ont le même comportement. – Joel

L'erreur suivante:

SIGSEGV (0xb) at pc=0xb70f0ca7, pid=5065, tid=2145643376

montre que quelque part, vous accédez à une adresse mémoire invalide ou NULL de ID de processus (5065) (non pertinent pour le moment).

Donc, si vous programmez un robot, cela signifie que vous êtes soit:

  • En utilisant une bibliothèque (DLL) qui peut communiquer à un port série pour accéder à ce robot, votre code pour parler à la bibliothèque est probablement passer une valeur NULL qui, à son tour, se bloque dans la DLL.
  • Écrire votre propre bibliothèque native qui accède alors à une adresse mémoire NULL ou invalide.

La machine JVM tombe alors en panne. Je ne peux pas vous aider plus loin parce que je ne sais pas comment vous avez programmé (en Java) pour communiquer avec votre robot, alors ce n'est qu'une enquête.

En savoir plus sur SIGSEGV.

Vous exécutez le correctif Java 1.6.0 15. La dernière version du correctif (correctif Java 1.6.0 18) contient des correctifs pour un certain nombre de bogues de panne de la JVM en fonction des notes de version. Donc ça vaudrait la peine d'essayer une mise à niveau. Toutefois, la théorie selon laquelle vos problèmes sont causés par un code JNI flakey est également plausible.

Voici une documentation Sun sur Troubleshooting System Crashes pour Java 6.
