[Bug] Delayed message isn't marked as acked when delayed time > messageTTL

[visxu]

Search before asking

• I searched in the issues and found nothing similar.

Read release policy

• 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

OS: MAC 13.6.7
Java: 17
Pulsar: 3.0.6

Minimal reproduce step

1. Create a topic and set messageTTL 60s
2. Start a consumer on the topic
3. Send a delayed 120s message

What did you expect to see?

The consumer will not receive the delayed message.

What did you see instead?

Consumer consumed the delayed message.

Anything else?

I sent a delayed 120s message with timestamp, but got it 2 mins later.

Are you willing to submit a PR?

BTW, according the doc, seems the delayed message should be auto acked if TTL expires.

https://pulsar.apache.org/docs/3.0.x/concepts-messaging/#delayed-message-delivery

[visxu]

Additionally, I didn't set TTL on namespace level.
