Matt Juntunen commented on MATH-1449:
-------------------------------------

Sounds good. I just updated the pull request with those changes. I'll include 
updates to other tests in future commits on MATH-1437.

> The o.a.c.m.geometry.euclidean.twod.PolygonsSet.getBarycenter() method 
> returns the point (0, 0) when the region is empty. It should return (NaN, 
> NaN) since the barycenter does not exist. This is the behavior of 
> IntervalsSet and PolyhedronsSet.
