Strange, it seems to be this one:
https://issues.apache.org/jira/browse/FLINK-5363
> Fire timers when window state is currently empty
> ------------------------------------------------
>
> Key: FLINK-5363
> URL: https://issues.apache.org/jira/browse/FLINK-5363
> Project: Flink
> Issue Type: Bug
> Components: DataStream API
> Reporter: Aljoscha Krettek
> Priority: Major
> Labels: pull-request-available
>
> Currently, when a {{Trigger}} sets a timer and that timer fires in the future
> at a point when there is currently no data in the window state, then that
> timer is being ignored.
> This is a problem for some users because they manually set cleanup timers and
> they need to be called because the trigger needs to cleanup some state. (For
> normal time windows this is not a problem, but for special cases built on top
> of {{GlobalWindows}} the current behaviour leads to problems.)
