Aljoscha Krettek commented on FLINK-13926:
------------------------------------------
It's unfortunate that we have this discrepancy now but I think we cannot change
the signatures of those classes because it might require changes in user code.
I would like to ignore that unless absolutely necessary.
I'm closing this for now but please re-open if you feel strongly about it, you
could then add it to this umbrella issue: FLINK-3957.
> `ProcessingTimeSessionWindows` and `EventTimeSessionWindows` should be
