current implementation of commit and abort do not handle critical exception and try to recycle/reuse
the producer.

 

Kafka doc [https://kafka.apache.org/11/javadoc/index.html?org/apache/kafka/clients/producer/KafkaProducer.html]

recommends catch critical exceptions and should not recycle the producer.
{code:java}
catch (ProducerFencedException | OutOfOrderSequenceException | AuthorizationException e) 
{code}
