[Bug] Cannot receive txn message after previous message be aborted

[SmileYun]

Expected behavior

1. Receive committed messages
2. Even if the producer send a normal message, consumer cannot receive an abort message

Actual behavior

0. Start a consumer Output:

1. Send 3 normal messages (seq: 0,1,2) Msg received: Normal msg. seq: 0 Msg received: Normal msg. seq: 1 Msg received: Normal msg. seq: 2

2. Send 3 txn messages (seq: 0: commit,1: abort, 2: commit) Msg received: Transaction msg with commit. seq: 0

But also expect the message of seq 3 should be received.

3. Send 3 normal messages Msg received: Transaction msg with abort. seq: 1 ** // <----- should not be received ** Msg received: Transaction msg with commit. seq: 2 Msg received: Normal msg. seq: 0 Msg received: Normal msg. seq: 1 Msg received: Normal msg. seq: 2

Steps to reproduce

// pseudo code

• Consumer:

client := pulsar.NewClient({EnableTransaction: true})
consumer, err := client.Subscribe(pulsar.ConsumerOptions{
		Name:                              "consumer",
		Topic:                             tp,
		SubscriptionName:                  "consumer-sub-name", // consumeArgs.SubscriptionName,
		EnableBatchIndexAcknowledgment:    true,                // consumeArgs.EnableBatchIndexAck,
		EnableAutoScaledReceiverQueueSize: false,               // consumeArgs.EnableAutoScaledReceiverQueueSize,
		Type:                              pulsar.Exclusive,    // consumeArgs.SubscriptionType,
		SubscriptionMode:                  pulsar.NonDurable,   // consumeArgs.SubscriptionMode,
		SubscriptionInitialPosition:       pulsar.SubscriptionPositionEarliest,
		AckWithResponse:                   true,
	})
for msg := range consumer.Chan() {
log.Infof("Msg received: %v", string(msg.Payload()))
} 

• Producer:

producer, err := client.CreateProducer(pulsar.ProducerOptions{
		Name:                    "p-name",
		Topic:                   tp,                     // produceArgs.Topic,
		MaxPendingMessages:      10,                     // produceArgs.ProducerQueueSize,
		BatchingMaxPublishDelay: 500 * time.Millisecond, // time.Millisecond * time.Duration(produceArgs.BatchingTimeMillis),
		BatchingMaxSize:         uint(1024 * 1024 * 10), // produceArgs.BatchingMaxSize * 1024,
		BatchingMaxMessages:     1024,                   // produceArgs.BatchingNumMessages,
		SendTimeout:             0 * time.Second,
		CompressionType:         pulsar.LZ4,
	})
isInTx := true
ack := "commit" // // means: err = tx.Commit(context.TODO()) 
sendMsg(client, producer, isInTx, ack, "0")

ack = "abort" // means: err = tx.Abort(context.TODO()) 
sendMsg(client, producer, isInTx, ack, "1")

ack = "commit"
sendMsg(client, producer, isInTx, ack, "2")
