After installing Fedora 12 from netinstall cd with KDE and LXDE, all my fonts are smoothed by default, except for java applications running under OpenJDK. To make them antialiased I have to turn on antialiasing manually in System Settings -> Look & Feel -> Appearence -> Fonts. Instead of system default, I select enabled, and at this point antialiasing gets turned on also in OpenJDK Was tested with OpenJDK Runtime Environment (IcedTea6 1.6) (fedora-33.b16.fc12-i386) OpenJDK Client VM (build 14.0-b16, mixed mode) and Netbeans 6.8 and other apps.
This could be a regression from 11, because fonts in Java applications got ugly after I upgraded from F11.
