BewareMyPower opened a new issue, #16195:
URL: https://github.com/apache/pulsar/issues/16195

   **Describe the bug**
   Sometimes a large message cannot be split into chunks and then failed to pass the `isMessageSizeExceeded` check. It's a bug introduced from PIP-132 (https://github.com/apache/pulsar/pull/14007).
   
   **To Reproduce**
   
   Add the following unit test to `MessageChunkingTest`:
   
   ```java
       @Test
       public void testChunkSize() throws Exception {
           this.conf.setMaxMessageSize(100);
   
           final Producer<String> producer = pulsarClient.newProducer(Schema.STRING)
                   .topic("my-property/my-ns/test")
                   .enableChunking(true)
                   .enableBatching(false)
                   .create();
           producer.send(createMessagePayload(60));
       }
   ```
   
   It will fail with 
   
   > The producer test-0-0 of the topic persistent://my-property/my-ns/test sends a message with 102 bytes that exceeds 100 bytes
   
   **Expected behavior**
   It should not fail. Instead, this message should be split into two chunks and sent successfully.
