> This is a regression due to FLINK-4280.
> In FLINK-4280, all initial offset determination was refactored to be consolidated at
the start of {{AbstractFetcher#runFetchLoop}}. However, this caused checkpoints that were
triggered before the method was ever reached to contain undefined partition offsets.
