---------------------------------------
I would like to contribute a test case and the fix to TimeWindow.intersects.
> TimeWindow.intersects return true for consecutive windows
> ---------------------------------------------------------
>
> Key: FLINK-15841
> URL: https://issues.apache.org/jira/browse/FLINK-15841
> Project: Flink
> Issue Type: Bug
> Components: API / DataStream
> Reporter: Jörn Kottmann
> Priority: Trivial
>
> The TimeWindow JavaDoc explains that the start index is inclusive and the end
> index is exclusive, therefore two windows T0 to T1 and T1 to T2 are next to
> each other without overlapping.
> To fix this the intersects comparison should be changed to: {{this.start <
> other.end && this.end > other.start}}
> Also a test should be added to verify the methods works correctly.
