   Since #6905 has been merged, it's now possible to create a schema that uses a custom ObjectMapper like so:
   
   ```
   val objectMapper= ObjectMapper()
   objectMapper.registerModule(KotlinModule())
   objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false)
   objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL)
   
   val schemDefinition = SchemaDefinition.builder<YourClass>()
               .withPojo(YourClass::class.java)
               .withSchemaReader(JacksonJsonReader(objectMapper, YourClass::class.java))
               .withSchemaWriter(JacksonJsonWriter(objectMapper))
               .build()
   ```
   
   Note that this only works with the unshaded version of the library (use org.apache.pulsar:pulsar-client-original instead of org.apache.pulsar:pulsar-client)
