The new sun-jdk-1.6 ebuild adds a link in KDE's kicker to easily access its control applet. This links merely points to "jControl", which I suppose would be a symlink in /usr/bin. However, such symlink doesn't exist, and the shortcut won't work. The icon is not set correctly either. An easy fix would be: ln -s /opt/sun-jdk-1.6.0/jre/bin/ControlPanel /usr/bin/jControl or manually modifying the kicker link so it points to the above location and setting the icon: /opt/sun-jdk-1.6.0/jre/plugin/desktop/sun_java.png Anyway, I'm just reporting this to make sure future revisions will fix the problem, as I'm very impressed with the Gentoo Java team. Your work has been remarkable, thanks for everything.
Looks like upstream changed the contents of desktop file since 1.5 and broke our sed customizations. Fixed in sun-jdk-1.6.0-r1, thanks for reporting!
