Yeah, here is a screenshot of my Java consumer application. (It should have received 3000 messages in total, and sometimes it works well.)  The code is ```java private static int receive(Consumer<byte[]> consumer) throws PulsarClientException { int n = 0; while (true) { final Message<byte[]> msg = consumer.receive(2, TimeUnit.SECONDS); if (msg == null) { break; } n++; System.out.println("Received " + new String(msg.getValue()) + " from " + msg.getMessageId() + ", key: " + msg.getKey()); } return n; } public static void main(String[] args) throws PulsarClientException { final PulsarClient client = PulsarClient.builder().serviceUrl("pulsar://localhost:6650").build(); final ConsumerBuilder<byte[]> builder = client.newConsumer() .topicsPattern(".*KeySharedConsumerTest-multi-topics.*") .subscriptionInitialPosition(SubscriptionInitialPosition.Earliest) .subscriptionType(SubscriptionType.Key_Shared) .subscriptionName("my-sub-1"); final Consumer<byte[]> consumer1 = builder.clone().subscribe(); final Consumer<byte[]> consumer2 = builder.clone().subscribe(); final Consumer<byte[]> consumer3 = builder.clone().subscribe(); int n1 = receive(consumer1); int n2 = receive(consumer2); int n3 = receive(consumer3); System.out.println("n1: " + n1 + ", n2: " + n2 + ", n3: " + n3 + ", total: " + (n1 + n2 + n3)); client.close(); } ``` But I cannot reproduce it with Java UT easily at the moment. -- This is an automated message from the Apache Git Service.
