jianyun8023 opened a new issue #9964:
URL: https://github.com/apache/pulsar/issues/9964


   **Describe the bug**
   
   Writing`schemaInfo#properties` may cause the client not to consume it when it is a Pulsar native type.
   
   **To Reproduce**
   Write `key` to `SchemaInfo#properties` has value, `value` is null, update schema. create subscriber will fail, throw NPE.
   example code :
   ```
   public static void main(String[] args) throws PulsarClientException, PulsarAdminException {
           final String topicName = "persistent://public/default/newtopic123" + RandomStringUtils.randomNumeric(4);
           Schema schema = Schema.INT32;
           final SchemaInfo schemaInfo = schema.getSchemaInfo();
           Map<String, String> map = new HashMap<>();
           map.put("key", null);
           schemaInfo.setProperties(map);
           final PulsarAdmin pulsarAdmin = PulsarAdmin.builder().serviceHttpUrl("http://127.0.0.1:8080").build();
           pulsarAdmin.topics().createPartitionedTopic(topicName, 1);
           pulsarAdmin.schemas().createSchema(topicName, schemaInfo);
           System.out.println(
                   "pulsarAdmin.schemas().getSchemaInfo(topicName) = " + pulsarAdmin.schemas().getSchemaInfo(topicName));
           try (
                   PulsarClient pulsarClient = PulsarClient.builder()
                           .serviceUrl("pulsar://localhost:6650")
                           .build();
   
           ) {
   
               final Consumer consumer = pulsarClient.newConsumer(Schema.INT32).topic(topicName)
                       .subscriptionName("consumer")
                       .subscribe();
           }
       }
   ```
   
   Console output.
   
   ```

   ```
   
   After troubleshooting once, the problem occurs with the `schemaInfo.toString()` implementation. Trying to call the same NPE occurs
   
   
   **Expected behavior**
   Normal creation of consumer consumption messages
   
   **Screenshots**
   If applicable, add screenshots to help explain your problem.
