Actually, depending on the time step, you can miss some collisions when using "a posteriori" discrete collision detection, it's not a bug, it's a known limitation.

I advise you to look at the source code of the wake up collision system and to display the data of the moving volume each time you move it. Compare it with the fixed bounding volumes. Make the collision test by yourself to ensure that there are really 2 collisions at the same time even though Java3D indicates only one.
