> 2) the inflight producer batch is expired when deliveryTimeoutMs has reached.
> The sender fail the producer batch via "failBatch" and the producer batch
> is deallocated via "accumulator.deallocate(batch)".
> 3) the response for the batch finally arrived after batch expiration, and the
> response contains the error "Errors.MESSAGE_TOO_LARGE" .

> time. As a result, the "IllegalStateException" will be raised.
