Sounds good!

Why not upgrade to kryo 4, with {{kryo.getFieldSerializerConfig().setOptimizedGenerics(true);}}?
The main advantage would be better java8 support I'd say, plus some fixes, especially for
generics handling (as long as users could also set {{kryo.getFieldSerializerConfig().setOptimizedGenerics(false);}}.

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 Flink's Kryo version is outdated and could be updated to a newer version, e.g. kryo-3.0.3.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