This sounds like a problem with the view clip limits (set on the View object).
If the ratio:
backClipDistance / frontClipDistance
Is too large, objects that are near the back clip plane will loose their depth
buffer resolution just as you describe. Make sure that the back/front ratio is
less than 3000 to avoid this effect. You may need to make this ratio even
smaller if you have objects that are very close together near the back plane.
Note that this is a property of the mathmatics used for viewing 3D objects, so
that this problem is common to all 3D graphics libraries, not just Java3D.
