take a look: ls -ll /usr/share/java | grep swt.jar it's a link pointing to another link: "swt.jar -> /etc/alternatives/swt.jar" but if you look at that new link: ls -ll /etc/alternatives/ | grep swt.jar it's pointing to an inexistent file: swt-gtk-3.2.1.jar the correct file is "/usr/share/java/swt-gtk-3.2.2.jar" so it seems to be a bug on the swt package. but you can fix it doing: update-alternatives --set swt.jar /usr/share/java/swt-gtk-3.2.2.jar -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
