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.

> Update Kryo version from 2.24.0 to 3.0.3

>             Project: Flink
>          Issue Type: Improvement
>          Components: Build System
>    Affects Versions: 1.0.0
>            Reporter: Maximilian Michels
>            Priority: Minor
>             Fix For: 1.0.0
> Flink's Kryo version is outdated and could be updated to a newer version, 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.
