The only news I'm aware of is that JSR-184 is in Community review phase.
The spec can be found at: http://www.jcp.org/en/jsr/detail?id=184&showPrint
OpenGL-ES info can be found at: http://www.khronos.org/
JSR-184 isn't a subset of Java3D (although it is Java, 3D, and scenegraph
based).

Did you hear any news about that new media api JSR-184(the one that is a
scenegraph subset of java 3d modified+opengl)? There is apparently supposed
to be some news about that and I'm wondering if there was anything cool

There was nothing to get from the stack trace. What you get was exactly what

my case, and probably your too, is 24 bit z-buffer.

Your new code looks the same on the graphics display - the top row is a

Alessandro,
I've tested on a "16MB ATI Rage 128 Ultra" for you. I do get seven
spinning cubes and one "failure"? labeled: 32, (blank with "depthBuffer
32 Failed!"), 24, 16, 12, 10, 8, 0. So I'm not sure if it failed on
anything or not. Are you testing 32 bit in two ways?

Hm. I've just learned that my video card GeForce2 MX 200 doesn't support 32
bit Z-buffers. Thanks Alessandro for the test program. Although I see the
cube in all 7 boxes, the output of the program is pretty clear: in the case
of the 32 bit Z-buffers it has defaulted to 24.
