Review comment:
This seems like fixing one specific case that was discovered. There is
probably a ton of unsupported cases. I would suggest that we either:
- See why this is a problem in the first place (classes should not be
serialized into savepoints or should not be in the serializers any more).
- Do not support Scala version switches with savepoint compatibility (due
to scala)
