Stephan. OK, that sounds very interesting. I'll have to read the code to fully understand.

Robert, in case some newbie like me pops in again. The issue (although the exception's stack
trace is not at all informative) is that I had cloned Flink as a git sub-module and JGit was
failing  to walk a higher git ref tree for some reason. Common solutions posted on line are
to add a random commit, although this didn't work in my case. 

Fabian, thanks that's solved the issue. Unfortunately not the algorithm :(

Also. You guys are amazingly hard working.

The non-solution set side is preserved in an outer-join fashion.

The solution set is carried forward into the next iteration, but it is not
part of the "outer join" result.
