Found in 2.0.0-milestone4. When attempting to deserialize a cloud event consumed via a Kafka consumer.

Caused by: java.lang.NullPointerException: Cannot invoke "io.cloudevents.rw.CloudEventDataMapper.map(io.cloudevents.CloudEventData)" because "mapper" is null

I guess it's a duplicate of #259, reopen if you need it
