> The GroupReduceITCase has an error that allows a problem with {{null}} Dates to go uncovered:
> If I set the parallelism to 1 in {{testDateNullException()}} and all keys actually end up on the same operator, then there is a problem in the de/serialization.
> It seems that {{null}} values are somehow skipped by the serialization process (e.g. maybe no {{null}} indicator is written), which leads to wrong deserializations.
