--------------------------------------------------------------

[~martijnvisser] this PR upgrades Flink from Kryo v2.x to Kryo v5.x and preserves backward compatibility with existing savepoints and checkpoints: [https://github.com/apache/flink/pull/22660]

 

This keeps the Kryo v2 project dependency for backwards compatibility only and otherwise uses Kryo v5.x.

> Flink's Kryo version is outdated and could be updated to a newer version, e.g. kryo-3.0.3.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.
