positive.code: Previously we've seen the usage of `ObjectMapperSerializer` to serialize objects via Jackson.
  For the corresponding deserializer class, we need to create a subclass of `ObjectMapperDeserializer`.
  
  You may have noticed the deserializer configuration on the previous step specifying `org.acme.kafka.model.QuoteDeserializer` class.
  So, let's create it inside `producer` project on `src/main/java/org/acme/kafka/model/QuoteDeserializer.java`
  
  [source,java]
  
negative.code:     }
  }
  ----
  
  No need to add any configuration for this inside `application.properties` file.
  Quarkus will automatically detect this serializer.
