Github user jaoki commented on the pull request: https://github.com/apache/flink/pull/1355#issuecomment-156867821 @StephanEwen , thank you for your feedback. Looping with an int variable is clearly wrong in Flink's use case, and I can change to long, but, I'd like to hear more of this refactor. I'd withdraw this PR if it is not what the community prefer at the first place. Let me know!
