Comment (by mdavis):

 This is due to an issue in the underlying Delaunay triangulation
 computation, caused by some very close sites.  This isn't fixed by the
 recent Voronoi bug fix, which was a fix for the circumcentre calculation
 in the Voronoi code.

 The upstream JTS issue is:  https://github.com/locationtech/jts/issues/20
