Description

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.
