Stephan Ewen commented on FLINK-940:
------------------------------------

I have tried your sample code in both variants (co group first and second).

I get the exact same results both times. Both with version 0.5.1 and 0.6-SNAPSHOT

I ran it on degree-of-parallelism 4.

> If I execute a coGroup on a SolutionSet, the grouping doesn't find any matching tuples, but if I reverse the grouping(SolutionSet as second set), matching tuples are found.
