> Message deserialization is currently done in the FetchResponse handler which is executed
by NetworkClient. Unfortunately, this means that any exceptions raised by the deserializer
will be eaten by NetworkClient and not raised to users. This will be fixed (if unintentionally)
in KAFKA-3888, but we should make sure that this is fixed in 0.9.0 and 0.10.0 as well.
