Java WebStart NPE occasionnel depuis 1.8 031
Nous avons une application Java signée qui est distribuée aux clients avec Java WebStart, mais depuis 1.8_031, nous voyons parfois un NPE. Avec Java 1.8_031 ou une version antérieure, l'application a toujours fonctionné. La même machine peut parfois exécuter l'application, parfois pas. Effacement du cache n'a pas d'incidence sur cette question.
Le fichier JNLP se présente comme suit:

J'ai essayé de reconditionner le fichier JNLP même s'il est déjà conforme à la norme car nous avons d'autres fichiers jnlp d'application qui fonctionnent sans erreur, mais sans succès.
Toute entrée appréciée.
