I am using Fedora 19 with firefox and google-chrome browser with Icedtea-web plugin for java applets execution. Currently I am not able to see this (http://www.formula1.com/live_timing/live_timing.html) website which requires Icedtea-web and I encounter this error while trying to load the applet. The site works well on Fedora 18. The folloing exception has occured. For more information, try to launch the browser from the command line and examine the output. For even more information you can visit http://icedtea.classpath.org/wiki/IcedTea-Web and follow the steps described there on how to obtain necessary information to file bug Another available info: IcedTea-Web Plugin version: 1.4 (fedora-0.fc19-x86_64) 5/27/13 8:37 PM Exception was: net.sourceforge.jnlp.LaunchException: Fatal: Initialization Error: Could not initialize applet.
