Aide à la compréhension de la sortie jstack

2010-08-26 3 views
6

J'ai une application Java/Swing de bureau qui est déployée via Java Webstart (les clients utilisent Java 6u20 sous XP). J'ai reçu des rapports intermittents des utilisateurs de l'application suspendue. J'ai réussi à me connecter à un tel système au cours d'un blocage constaté que l'interface n'était pas en train d'être tirée (comme si EDT était bloqué). J'ai utilisé jstack pour lister les threads; Je ne vois aucune mention de deadlocks sur la sortie et depuis que je suis tout à fait nouveau à jstack je ne sais pas quoi d'autre je devrais rechercher.Aide à la compréhension de la sortie jstack

J'ai dû modifier la trace de la pile pour lui permettre de respecter les limites stackoverflow, je l'espère rien de significatif n'a été laissé.

Merci,
Phil

Vous avez probablement courir en bogue 6960427, qui a été signalé contre 1.6.0_20 (problème de verrouillage mort).

Etes-vous sûr que la trace de la pile affichée est terminée? Vous avez plusieurs threads en attente de verrouillage sur 0x1d485f80, mais pas de thread avec un verrou réel sur ce moniteur.

Il semble que ce soit un verrou différent qui soit à l'origine du problème, mais apparenté. –

Salut, excuses pour le retard dans la réponse, je viens de lire les réponses maintenant. En ce qui concerne le verrouillage sur 0x1d485f80, j'ai coupé ce droit, il est détenu par thread 0x05913400. Il ressemble à ce qui suit: \t - verrouillé <0x1d485f80> (un com.sun.deploy.security.CPCallbackHandler $ ParentCallback) – PhilDin

[S'il vous plaît ignorer le commentaire ci-dessus, voici le prévu] Salut, excuses pour le retard dans la réponse, je viens de lire les réponses maintenant. En ce qui concerne le verrouillage sur 0x1d485f80, j'ai coupé ce droit, il est détenu par thread 0x05913400. Il se présente comme suit: \t - <0x1d485f80> verrouillé (un ParentCallback com.sun.deploy.security.CPCallbackHandler $) Ai-je raison interpretting cela signifie que le type d'objet verrouillé est un ParentCallback? Cela ressemble au bug 6960427 mais je remarque que dans le rapport de bug, il liste un blocage à la fin, ma sortie jstack n'en identifie aucune. – PhilDin

Il y a beaucoup de fil prétendant

- waiting to lock <0x1d485f80> (a com.sun.deploy.security.CPCallbackHandler$ParentCallback)

Est-ce lieu quelque part dans la sortie snipped?

Il semble que vous mélangez intentionnellement le code de confiance et non fiable (« code mixte »), ce qui est une mauvaise chose. A partir de 6h19, une boîte de dialogue d'avertissement est affichée (la tentative devrait être automatiquement bloquée, mais il semble y avoir beaucoup de code qui exploite le bogue). C'est cette boîte de dialogue d'avertissement qui semble causer le problème.

Pour fixer, ne pas mélanger le code de confiance et non fiable. C'est une bonne idée d'ajouter "Trusted-Only: true" au manifeste de chaque pot.

Salut Tom, J'ai eu des problèmes avec les avertissements de code de confiance/non fiables mais ce n'est pas intentionnel. J'ai signé tous les pots (le mien + troisième partie) avec un cert auto-signé, donc je ne m'attendais pas à ce que ce soit un problème. Puis-je vous demander comment vous pouvez le dire à partir de la sortie de la pile (est-ce la ligne 16.3-b01 en mode mixte, partage?) Deuxièmement, comment pouvez-vous dire à partir de la sortie que le dialogue d'avertissement est le problème? Merci. – PhilDin

Les traces de la pile incluent des expressions telles que 'showMixedTrustDialog' et d'autres threads semblent bloquer dans le code de déploiement lors du chargement des classes. "16.3-b01 mode mixte, partage" se réfère à la version de HotSpot (maintenant découplée de la version JRE), le fait qu'il utilise à la fois le compilateur bytecode et l'interpréteur, et le partage est "Class Data Sharing" qui est l'utilisation de les 'classes.fichier jsa' qui accélère les performances de démarrage. Comme je l'ai dit, si vous ajoutez «Trusted-Only: true» à vos manifestes, cela devrait empêcher le chargement de code non fiable, qu'il soit involontaire ou hostile. –
