> This happens for example when a sort feeds into a merge join and the merge join exits early (zig zag merge determined that it can stop).
> You can reproduce this bug by running the transitive closure in Scala (or Java with an enforced merge join) using the following toy data set.
> {code}
> Path(2, 1),
> Path(4, 1),
> Path(6, 3),
> Path(8, 3),
> Path(10, 1),
> Path(12, 1),
> Path(14, 3),
> Path(16, 3),
> Path(18, 1),
> Path(20, 1) );
> {code}
