I don't have experience with OSX and Windows, but for GNU/Linux this has
been certainly possible for a couple of years already. Others did do
such things for other platforms.

The compiler accepts any modern java language feature, the class
libraries are somewhere between 1.5 and 1.6 depending on package. There
are currently no concrete plans to augment the classes with some of
Sun's new GPLed code. But there has already been a patch to make use of
the OpenJDK javac compiler directly (but that hasn't been integrated
yet).

Certainly, this has been possible for a long time now (a quick search
reveals that people have been doing that since 2003). It would be a
regression if that breaks. In fact the whole eclipse suite can be
compiled and run with gcj.
