Ignacio Vera commented on LUCENE-8534:
--------------------------------------
I had another go and now I can easily reproduce the issue:
{code:java}
public void testSmallPolygonTessellation() throws Exception {
Polygon poly = GeoTestUtil.createRegularPolygon(0.0, 0.0, 1, 2500);
assertTrue(Tessellator.tessellate(poly).size() > 0);
}{code}
Note that I am creating very tiny polygon with quite a lot of points. I think
the logic expect all points to have different Morton values which is not the
case here. Maybe the definition of point equality needs to be changed.
[~nknize], WDYT?
