Alan Ezust, Slava Pestov, Björn "Vampire" Kautler, Marcelo Vanzin, Matthieu Casanova, Eric Berry, and Eric Le Lay have released jEdit 4.3, a free-as-in-speech (GPL 2.0) programmer's editor written in Java with extensive plug-in support and my preferred text editor on Windows and Unix (though still far behind TextMate and BBEdit on the Mac.) Java 5 or later is now required.
