Problem starting yed with Java Web Start

0 votes

I always start yed with the java web start. But now an exception appears during start. The error reporting says the following:

I have already tried to remove the yWorks certificate from the java certificate cash, but this hadn't had any effect.

What could be the problem?

The problem appeared with

java version "1.7.0_05"
Java(TM) SE Runtime Environment (build 1.7.0_05-b05)
Java HotSpot(TM) Client VM (build 23.1-b03, mixed mode, sharing)

Hi, there seems to be a problem with the cached files of webstart application when updating from Java 6 to Java 7:

Deleting the applet cache through the control panel should resolve the problem.
