Il semblerait que certains utilisateurs expérimentent le bug JDK-8060036 du compilateur JIT du Java 8 (update 45).

Lien externe: https://bugs.openjdk.java.net/browse/JDK-8060036

Ce bug ne provient pas du logiciel BeDesk lui-même. Toutefois, BeDesk a besoin de Java pour fonctionner correctement.

Concerne la méthode javax.swing.text.GlyphView.getBreakSpot dans le fichier GlyphView.java à la ligne 799...

---

Un workaround consiste à désactiver la compilation JIT pour cette méthode.

Pour cela, ajouter le paramètre suivant dans la commande de démarrage du Java:

-XX:CompileCommand=exclude,javax/swing/text/GlyphView,getBreakSpot

---

Nous sommes en contact avec quelques utilisateurs où nous supposons avoir détecter le problème et des tests sont en cours.

---

Le workaround fonctionne. Reste plus qu’à l’intégré dans la prochaine mise à jour.
