so i noticed something with my graphics card and java a while back (nvidia 6800 ultra). when i started up java apps or when java kicked on in my web browser, my screen got blurry. turns out this is a bug with the way that java uses d3d. info here. turns out that you can work around this by turning off global anti-aliasing. i hope they fix this at some point so that i don't have to change my settings to get AA working in games that don't support it.
