Stephan Ewen commented on FLINK-3154:
-------------------------------------

I would like to close this as "won't fix".
This can only be addressed as part of a bigger initiative to introduce versioning for serializers,
otherwise we break all savepoint compatibility.

> Flink's Kryo version is outdated and could be updated to a newer version, e.g. kryo-3.0.3.
> From ML: we cannot bumping the Kryo version easily - the serialization format changed
(that's why they have a new major version), which would render all Flink savepoints and checkpoints
incompatible.
