this problem is occurring quite frequently on the mac also....
a workaround is
// --------------------------------------------- com.mw3d.core.spatial.SpatialDebuger : line 87
BoundingBox box = (BoundingBox) selectedGeometry.getWorldBound();
if(box == null)
{
// just dump any type of box otherwise Outline UI becomes unusable
box = new BoundingBox(selectedGeometry.getWorldTranslation(), 100f, 100f, 100f);
}
// ---------------------------------------------
however this affects picking etc...
it seems that jme is not calculating the bounds of the particles correctly, as getWorldBounds on the selected particle geometry returns null...
i've had issues with particles and bounds before and was advised only to use bounding boxes so it seems there may be problems there yet....
