This fixes will get in eventually, we'll try to make it for next release (after 1.3). They will have to be merged into another branch.

@snodnipper It's just we have certain internal code that needs to be updated manually. I'll try to make the process easier.

@nsiatras Is this the behavior that you want? http://esri.github.io/geometry-api-java/doc/Buffer.html If yes, then this is a sample code: { Polygon polygon = new Polygon(); //added one exterior ring (must be clockwise)...

@nsiatras Buffer operation does not remember the original vertices, so there is no way to obtain those directly from the buffer polygon.

In some more complicated cases the arcs intersect with each other and only partial. That happens when the polygon border has a lot of details and the buffer width is...

Yes, this is unfinished code, I forgot to remove it. We don't have a requirement to support this behavior in the OperatorUnion. The only place where this behavior was needed...

5. For ST_Covers, try using OperatorRelate with "******FF*". Although I am not 100% sure it is equivalent. See also here: https://en.wikipedia.org/wiki/DE-9IM. 6. Use operators. They are a part of the...

Should be "*****FF *". Try this though. I cannot think of a case it violates for non-empty inputs.

It keeps removing the last star...

Note, I've added a space to workaround the removing the star character. The string should not contain any spaces.
