Hilfe mit dem Verständnis der JStack-Ausgabe

2010-08-26 16 views
6

Ich habe eine Desktop-Java/Swing-Anwendung, die über Java-Webstart (Clients verwenden Java 6u20 unter XP) bereitgestellt wird. Ich habe intermittierende Berichte von Benutzern der Anwendung erhalten. Ich habe es geschafft, mich bei einem solchen System an einem solchen System anzumelden, und festgestellt, dass die Benutzeroberfläche nicht gezeichnet wurde (als wäre EDT blockiert).Hilfe mit dem Verständnis der JStack-Ausgabe

Ich benutzte Jstack, um die Threads aufzulisten; Ich sehe keine Hinweise auf Deadlocks auf der Ausgabe und da ich ziemlich neu bin, bin ich mir nicht sicher, was ich sonst noch suchen sollte.

Ich musste den Stack-Trace so bearbeiten, dass er in die Stackoverflow-Grenzen passt, hoffentlich wurde nichts Bedeutungsvolles weggelassen.

Danke,
Phil

Sie wahrscheinlich in Bug ausgeführt haben 6960427, die gegen 1.6.0_20 (Dead-Lock Ausgabe) berichtet wurde.

Sind Sie sicher, dass der Posted Stack Trace abgeschlossen ist? Sie haben mehrere Threads warten auf 0x1d485f80 zu sperren, aber kein Thread mit einer tatsächlichen Sperre auf diesem Monitor.

Es scheint eine andere Sperre zu sein, die das Problem verursacht, aber verwandt ist. –

Hallo, Entschuldigung für die Verzögerung beim Antworten, ich muss jetzt nur die Antworten lesen. In Bezug auf die Sperre auf 0x1d485f80, schneide ich das in Ordnung, es wird von Thread 0x05913400 gehalten. Es sieht wie folgt aus: \t - gesperrt <0x1d485f80> (ein com.sun.deploy.security.CPCallbackHandler $ ParentCallback) – PhilDin

[Bitte ignorieren Sie den obigen Kommentar, hier ist der beabsichtigte] Hallo, Entschuldigung für die Verzögerung in der Antwort, ich habe gerade um die Antworten jetzt zu lesen. In Bezug auf die Sperre auf 0x1d485f80, schneide ich das in Ordnung, es wird von Thread 0x05913400 gehalten. Es sieht wie folgt aus: \t - gesperrt <0x1d485f80> (ein com.sun.deploy.security.CPCallbackHandler $ ParentCallback) Bin ich richtig bei der Interpretation dies bedeutet, dass der Typ des Objekts gesperrt ist ein ParentCallback? Es sieht ähnlich aus wie der Fehler 6960427, aber ich merke, dass es im Fehlerbericht einen Deadlock am Ende auflistet, meine Jstack-Ausgabe identifiziert keine. – PhilDin

viel Faden Es ist behauptet

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

Ist das irgendwo in der snipped Ausgang gehalten?

Es scheint, als ob Sie absichtlich vertrauenswürdigen und nicht vertrauenswürdigen Code ("gemischter Code") mischen, was ein böses Ding ist. Ab 619 wird ein Warndialog angezeigt (eigentlich sollte der Versuch automatisch blockiert werden, aber es scheint viel Code da draußen zu sein, der den Fehler ausnutzt). Dieses Warndialogfeld scheint das Problem zu verursachen.

Um zu beheben, mischen Sie nicht vertrauenswürdigen und nicht vertrauenswürdigen Code. Es ist eine gute Idee, dem Manifest jedes Krams "Nur vertrauenswürdig: Wahr" hinzuzufügen.

Hallo Tom, ich hatte Probleme mit vertrauenswürdigen/nicht vertrauenswürdigen Code Warnungen, aber das ist nicht beabsichtigt. Ich habe alle Gläser (meine eigene + dritte Partei) mit einem selbst signierten Zertifikat unterschrieben, so dass ich nicht erwartet habe, dass dies ein Problem darstellt. Darf ich fragen, wie Sie dies über die Stack-Ausgabe sagen können (ist es die "16.3-b01 Mixed-Mode, Sharing" -Zeile oben?) Zweitens, wie können Sie anhand der Ausgabe feststellen, dass der Warndialog das Problem ist? Vielen Dank. – PhilDin

Die Stack-Traces enthalten "showMixedTrustDialog" und andere Threads blockieren beim Laden von Klassen den Bereitstellungscode. "16.3-b01 mixed mode, sharing" bezieht sich auf die Version von HotSpot (jetzt entkoppelt von der JRE-Version), die Tatsache, dass sowohl der Bytecode-Compiler als auch der Interpreter verwendet wird und die Freigabe von "Class Data Sharing" ist die 'Klassen.JSA-Datei, die eine schnellere Startleistung ermöglicht. Wie ich sage, wenn Sie Ihren Manifesten 'Nur vertrauenswürdig: wahr 'hinzufügen, dann sollte das stillschweigend das Laden von nicht vertrauenswürdigem Code verhindern, unabhängig davon, ob es sich um einen oder einen Widerpart handelt. –
