Ignacio Vera updated LUCENE-8070:
---------------------------------
Attachment: LUCENE-8070.patch
LUCENE-8070-test.patch
Attached is a test showing the issue and a possible solution.
The solution (I propose) tries to prevent such circles to be constructed. The
(maybe naive) assumption is that we should not allow circles that contain
antipodal points. I was hoping to find a way to know the shorter distance the
antipodal points on a planet but it seems harder than I expected. It seems to
work to choose the smaller distance between the poles of the planet (at least
for WGS84-like planets). What do you think?
P.S: I have changed the message of a thrown error as it should not be true any
more.

> Hi [~daddywri],
> I have seen test fail when we try to create circles that the don' t fit in
> the planet. I think sectors of the circle start overlapping to each other and
> the shape becomes invalid. The shape should prevent that to happen.
> I will attach a test and a proposed solution.
