hoi,
I did few experiments with gnu gcj java compiler.
It is not yet able to compile awt and swing code, but other important core libs work fine.
I also try it under win32 (cygwin) and it works well.
Did someone tried it already for something greater than “Hello World” 
What is your opinion?
I would like to try it out too.
Does Gcj(windows) supports swt.
Hmmm good question
How about LWJGL, does it run with GCJ too, because that would be da bomb
It should run with lwjgl, as an important design aspect of lwjgl is that it’s free of awt, swing etc. that can hinder native compilation.
I know that cas has compiled lwjgl programs with jet, so I see no problem using gcj to do the same.
LWJGL uses the NIO functions, right?
Last time I checked the GCJ site it mentioned that NIO is not fully implemented yet.
Thats why I asked ;D
hmm, yes - at http://gcc.gnu.org/java/faq.html#2_2 they state that the jni interface is ‘experimental’. I’m not sure what that means, nor how updated that FAQ entry is.
