Hi Could you please check if you have a broken swt symlink or is missing an swt.jar symlink in /usr/share/java[1]? The broken symlinks are usually fixed by reinstalling libswt-gtk-3.5-java. Please see #568940[2] for more information.
~Niels [1] The output of ls -l /usr/share/java/swt*.jar should do. You should have two symlinks named: /usr/share/java/swt-gtk-3.5.1.jar /usr/share/java/swt.jar and pointing to /usr/lib/java/swt-gtk-3.5.1.jar [2] http://bugs.debian.org/568940
