Ignacio Vera updated LUCENE-8071:
---------------------------------
    Attachment: LUCENE-8071.patch
                LUCENE-8071-test.patch

Attached the test and proposed solution.

I basically force the shape to create at least 4 sectors if the radius is big. I have realized as well that the shape has always a minimum of two sectors. Therefore there is a lot of code that can be removed as it is checking for number of sectors lower than 2.

> Hi [~kwright@metacarta.com],
> There is still a situation when the test can fail. It happens when the planet model is a SPHERE and the radius is slightly lower than PI. The circle is created with two sectors but the circle plane is too big and the shape is bogus.
> I will attach a test and a proposed solution. (I hope this is the last issue of this saga)
