    This was an historic artifact of the Flink 1.1 key and namespace 
serialization with RocksDB. I think we can remove this completely in a 
different issue.

>             Project: Flink
>          Issue Type: Improvement
>          Components: Queryable State
>    Affects Versions: 1.2.0

> KvStateRequestSerializer#deserializeKeyAndNamespace() throws an IOException, 
> e.g. EOFException, if the deserialisation fails, e.g. there are not enough 
> available bytes.
> In these cases, it should instead also throw an IllegalArgumentException with 
> a message containing "This indicates a mismatch in the key/namespace 
> serializers used by the KvState instance and this access." as the other error 
> cases.
