We could add an ITCase to make sure that the fix works. I am not saying
that this is the ideal way to test it, but it is definitely a way to get some
coverage over the time windowing code - even if it is going to change
eventually.

> Key: FLINK-2286
> URL: https://issues.apache.org/jira/browse/FLINK-2286
> Project: Flink
> Issue Type: Bug
> Components: Streaming
> Affects Versions: 0.9, 0.10
> Reporter: Márton Balassi
> Assignee: Gábor Hermann
> Fix For: 0.9.1
>
>
> Last windows in the stream that do not have parts at all the parallel
> operator instances get swallowed by the ParallelMerge.
> To resolve this ParallelMerge should be an operator instead of a function, so
> the close method can access the collector and emit these.
