**Describe the bug**  parse message metadata throw Exception **To Reproduce** Steps to reproduce the behavior: 1. start up a standalone pulsar, the version is bigger than 2.10.0 2. change broker config transactionCoordinatorEnabled=true managedLedgerMaxEntriesPerLedger=3 managedLedgerMinLedgerRolloverTimeMinutes=1 3. config namespace ttl ./pulsar-admin namespaces set-message-ttl -ttl 10 public/default 4. ``` int sendTopicsCount = 500; String topicName = "test"; List<Producer<String>> producers = new ArrayList<>(sendTopicsCount); for (int i = 0; i < sendTopicsCount; i++) { producers.add(pulsarClient.newProducer(Schema.STRING).sendTimeout(0, TimeUnit.SECONDS).topic(i + topicName).create()); Consumer<String> consumer = pulsarClient.newConsumer(Schema.STRING).subscriptionName("test").topic(i + topicName).subscribe(); consumer.closeAsync(); } for (int i = 0; i < sendTopicsCount; i++) { Transaction transaction = pulsarClient.newTransaction().withTransactionTimeout(10, TimeUnit.SECONDS).build().get(); System.out.println("send one transaction messageId" + producers.get(i).newMessage(transaction).value(i + topicName).send() + " topic name : " + i); transaction.commit(); producers.get(i).closeAsync(); Thread.sleep(100); }``` Execute the above code multiple times. Execute `./pulsar-admin namespaces unload public/default` multiple times. 4.
