do you mean you are using different snapshots, for AFAIK there is no
1.8.1 version ;)

is that a possibility, i.e. that you have a vertex at infinity in your
geometry ?

thanks for sending these, they are very helpful for understanding the
problem (unfortunately I'm less clear on what its cause is ;) ).

There was a change involving bounding boxes, they were incorrect for
Geometry that was not a leaf of the scene graph. To double check I just
took another look at that code and it looks ok to me.

I suppose the bounding boxes on the images you sent are drawn by the
RenderAction with setVolumeDrawing(true)? If you move closer to your
scene more of the interior bounding boxes should become visible, maybe
you could use that to narrow down which object (and if it is Geometry or
some other Drawable) has the incorrect bounding box ?
Hope it helps,
Carsten
