Major Description
I am following the producer with transactions example in https://kafka.apache.org/23/javadoc/org/apache/kafka/clients/producer/KafkaProducer.html, and on kafkaException, I use abortTransaction and retry.
In some cases, abortTransaction fails, with:
```
org.apache.kafka.common.KafkaException: Cannot execute transactional method because we are in an error state
```
as far as I can tell, this is caused by
```
org.apache.kafka.common.KafkaException: The client hasn't received acknowledgment for some previously sent messages and can no longer retry them. It isn't safe to continue.
```
Since both are KafkaException, the example seems to imply they are retriable, but they seem not to be. Ideally, I would expect abortTransaction to succeed in this case (the broker will abort the transaction anyway because it can't be committed), but at the very least, I would expect to have a way to determine that the producer is unusable and it can't recover.
