Is there another Sphere object already in the scene graph? By default
our geometry primitive utilities cache and share Geometry objects. So,
if one already exists in the scene graph, the Geometry could already
be live. A quick check is to check the value of Geometry.isLive().
To turn off this sharing, create the Sphere with the
Primitive.GEOMETRY_NOT_SHARED flag.
As for the SimpleUniverse case, many parts of the scene graph are made
live when a SimpleUniverse is created - specifically the view side of
the scene graph.
