Nico Kruber updated FLINK-11774:
--------------------------------
Comment: was deleted
(was: I actually occasionally also see this with the {{TopSpeedWindowing}}
example in Flink. I managed to get hold of a savepoint that was taken with
parallelism 2 (p=2) and shows a similar failure in two different ways (all
running in Flink 1.10.0; but I also see it in Flink 1.9):
* first of all, if I try to restore with p=2, everything is fine
* if I restore with p=4 I get an exception like the one mentioned above:

{code}
While the latter error somewhat indicates that the savepoint may be corrupt (or
that the reader/deserializer messed up), it remains a mystery to me why I can
successfully restore with p=2.)
