I updated from OpenJDK 7 to 8. I uninstalled 7, which uninstalled the IcedTea plugin as well. I tried to reinstall IcedTea with
sudo apt-get install icedtea-7-plugin
But it doesn't work. When I try to launch topcoder jnlp file, it fails. Also, it doesn't load any java plugin in Google Chrome. It was fine with OpenJDK 7. Is there a newer version of IcedTea for OpenJDK 8?
