> Project: Kafka
> Issue Type: Bug
> Reporter: Anjaneya Gupta
> Assignee: Shantanu
> Priority: Minor
>
> On the leader, KafkaRaftClient#appendBatch registers an asynchronous commit
> callback and then releases the batch's memory buffer back to the pool in a
> finally block. The callback runs later (once the batch commits) and reads
> CompletedBatch#appendTimestamp() out of that buffer. By then the buffer may
> have been reused by a newer batch, so the callback reads the newer batch's
> timestamp and delivers the wrong appendTimestamp to the commit listener.
