>
> In KafkaConsumer#commitAsync that does not take offset parameters, we have the following logic:
> {code:java}
> public void commitAsync(OffsetCommitCallback callback) {
> acquireAndEnsureOpen();
> try {
> commitAsync(subscriptions.allConsumed(), callback);
> } finally {
> release();
> }
> }
> {code}
> This function calls another commitAsync with default all consumed offset which also call `acquireAndEnsureOpen`.
