>
> If a custom deserializer returns an empty list of objects as a result of
> deserializing messages from kafka, the partition manager does not advance the
> kafka offset, and the same message will continue to be deserialized and
> return nothing. The code works if the deserializer returns null, but not if
> it returns an empty list.
