L'applet se bloque

Question

J'ai trouvé le message suivant Java 6 JVM Hang avec une exception quelque peu similaire que je reçois. Il n'y a pas d'impasse. Mais beaucoup de threads sont dans l'état WAIT. La trace de pile est la suivante. Mon client JRE est 1.6.0_18.

Answer 1

Vous avez threads en attente sur les instances de ilog.views.tiling.IlvThreadedTileLoader, donc il devrait y avoir d'autres discussions qui font notify. Difficile d'en dire plus sans voir le code.
