------------------------------------

or even better, migrate the IllegalArgumentException to IOException

> 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.
