Karl Wright commented on LUCENE-6759:
-------------------------------------

Ok, two issues.

First issue: the problem I was initially debugging was iteration 121.  This 
problem is occurring on iteration 122.  It's a different shape, and all the 
analysis/tests that were done are no longer pertinent.  I guess that's good.

For iteration 122, the shape is a GeoPath.  The problem is simply that the root 
cell does not contain document 1230.  Neither does the xyzbounds.  But the 
shape itself *does*.

Some debugging output:
{code}
   [junit4]   1> TEST: iter=122 shape=GeoPath: {planetmodel=PlanetModel.WGS84, 
width=0.7766715171374766(44.5), points={[[lat=-0.2751718361148076, 
lon=-0.7786721269011477], [lat=0.5728375851539309, lon=-1.2700115736820465]]}}
   [junit4]   1>   root cell: cell=36178 x: -1068861352 TO 2145533482, y: 
-2147483647 TO 66660163, z: -1855240006 TO 2086587766, splits: 0 contains 1230? 
false GeoArea contains 1230? false shape contains point? true maximum X > 
maxPlanet? false
   [junit4]   1>   doc 1230 encoding: x=2145533565 y=-84921712 z=-33945127
{code}

So, it's the x dimension that is insufficient; the x upper bound for the root 
cell is too small by 83.

I'll set this up in its own Geo3D test and analyze it further.
