Denovo1998 opened a new issue, #23149: URL: https://github.com/apache/pulsar/issues/23149
### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Read release policy - [X] I understand that unsupported versions don't get bug fixes. I will attempt to reproduce the issue on a supported version of Pulsar client and Pulsar broker. ### Version master ### Minimal reproduce step I found this when trying to implement the abort function of delayed messages. Here is the test code. ```java @Test(timeOut = 20000) public void testAbortDelayedMessage() throws Exception { final String topic = "persistent://my-property/my-ns/testAbortDelayedMessage"; Consumer<byte[]> consumer = pulsarClient.newConsumer().topic(topic) .subscriptionName("my-subscription") .subscriptionType(SubscriptionType.Shared) .subscribe(); Producer<byte[]> producer = pulsarClient.newProducer().topic(topic).enableBatching(false).create(); admin.topicPolicies().setDelayedDeliveryPolicy(topic, DelayedDeliveryPolicies.builder() .active(true) .tickTime(100L) .maxDeliveryDelayInMillis(5000) .build()); MessageId msgId = producer.newMessage() .value("Test delayed message".getBytes()) .deliverAfter(5, TimeUnit.SECONDS) .send(); log.warn("Message sent with ID: " + msgId); producer.flush(); consumer.acknowledge(msgId); while (true) { Message<byte[]> msg = consumer.receive(100, TimeUnit.MILLISECONDS); if (msg != null) { log.warn("Received message: " + new String(msg.getData())); consumer.acknowledge(msg.getMessageId()); } log.warn("Waiting for messages..."); } } ``` ### What did you expect to see? Delayed messages are consumed normally. Because consumer have not received this message. ### What did you see instead? After the delay message corresponding to the active ack is consumer, the delay message is no longer consumed. ### Anything else? Will there be any problem with ack like this? ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
