`TestHelpers.assertSerializedAndLoadedMetadata(table, 
TestHelpers.roundTripSerialize(table))` serializes the original table, but the 
second case the Serializable copy of it?

   I just realized that we don't need to do anything for 
`TestTableSerialization`. The test first uses Java ser/de for the `table` which 
is not a `SerializableTable`, hence it's expected that it fails with Kryo
