Irrlicht for Java. Now this is definitely nice. 
Let’s see how many scenegraph engines are out there for Java.
Irrlicht, Java3D, Xith3D, jME, and that’s all I have, but I do remember at least 2 extra which I don’t have a name for. One engine I can’t remember is pretty advanced and it’s commercial.
Java is definitely coming out of the dark ages in the gaming arena.
