I see two cases: 1) you expect that the value is 16 at line 96, then it changes to another value, then is it again back to 16 2) you are expecting that the value is never changing if it is 1) then you should add some assertion between this line and like 96 to check that the value is not 16 anymore if it is case 2) then you don't need `Awaitility.await().untilAsserted` but you can simply leave `assertEquals(dispatcher.getConsumers().get(0).getUnackedMessages(), 16);` ########## File path: pulsar-broker/src/main/java/org/apache/pulsar/broker/service/Consumer.java ########## @@ -811,8 +916,15 @@ public Subscription getSubscription() { } private int addAndGetUnAckedMsgs(Consumer consumer, int ackedMessages) { - subscription.addUnAckedMessages(ackedMessages); - return UNACKED_MESSAGES_UPDATER.addAndGet(consumer, ackedMessages); + int unackedMsgs = 0; + if (Subscription.isIndividualAckMode(subType)) { + subscription.addUnAckedMessages(ackedMessages); + unackedMsgs = UNACKED_MESSAGES_UPDATER.addAndGet(consumer, ackedMessages); + } + if (unackedMsgs < 0) { + log.error("unackedMsgs is : {}, ackedMessages : {}, consumer : {}", unackedMsgs, ackedMessages, consumer); Review comment: makes sense -- This is an automated message from the Apache Git Service.
