Robert Muir commented on LUCENE-7185:
-------------------------------------

I'm gonna try to fight my way thru the various test fails, some are pretty 
crazy.

by frequently choosing certain edge values it also means we find bugs or test 
bugs with tie-break handling in sorting, rectangles that really look more like 
lines/single points, you name it.

> fix random number generation used for spatial tests

> The current method is not very good for testing. 
> * It will only rarely or never return edge cases like -180/180/-90/90
> * It will only rarely return 0
> * There are many possible doubles within the ranges (-180..180/-90..90) it 
> will never return
