Yes, this is better. Also looking at the code the '4' should in
fact be Math.ceil(Math.log2(nCubes)) (the number of bits needed to
hold nCube values). So it should have been 8 in the original code,
I suspect the JDK fixes this, but the bug should be fixed.

This is fine. If you send me the diffs I'll look them over and
apply them.
