   It's an incorrect use to call a synchronous API in the callback of an asynchronous API.
   
   For example, the following Java code also causes the deadlock.
   
   ```java
           @Cleanup final var client = PulsarClient.builder()
                   .serviceUrl(Config.BROKER_URL)
                   .build();
           @Cleanup final var producer = client.newProducer(Schema.STRING)
                   .topic("my-topic")
                   .create();
           producer.sendAsync("hello").thenAccept(msgId -> {
               try {
                   producer.close();
                   System.out.println("Producer closed");
               } catch (PulsarClientException e) {
                   throw new RuntimeException(e);
               }
           }).get();
   ```
