   > @shiv4289 FYI. There is some minor issues in existing schema autoupdate policy test. But I still can't reproduce the issue you mentioned in the slack channel :(
   
   @sijie  I am using 2.3.1 java client. And I can reproduce simply with this:
   
       public static void main(String[] args) throws PulsarClientException {
           try {
               client = PulsarClient.builder()
                       .serviceUrl(PULSAR_BROKER_URL)
                       .build();
               
               producer = client.newProducer(AvroSchema.of(SampleCreated.class))
                       .topic(PULSAR_TOPIC)
                       .create();
           } catch (PulsarClientException e) {
               e.printStackTrace();
           } finally {
               producer.close();
               client.close();
           }
       }
   
   The schema is AVRO and  is part of the POJO SampleCreated.class
   
   1. Run the code above with an avro schema.
   2. Delete a field in the avro schema and use new POJO to create producer.
   
   The producer create will crash with 
   
   > org.apache.pulsar.client.api.PulsarClientException$IncompatibleSchemaException: org.apache.pulsar.broker.service.schema.IncompatibleSchemaException: Incompatible schema used
   
   Please let me know if you need any help in reproducing the issue with the java client.
