> As per [this discussion|http://mail-archives.apache.org/mod_mbox/kafka-users/201606.mbox/%3cCAHwHRrU29jw4jgVhSijWbVLZB3BC6Qz6pbH9TqCFBcoRJk4aZQ@mail.gmail.com%3e] these classes currently pass null values along to Deserializers, so those Deserializers need to handle null inputs and pass them through without throwing. It would be better for these classes to simply not call the Deserializers in this case; this would reduce the burden of implementers of {{Deserializer}}.
