I'm trying to add the circuit breaker pattern to a Kafka consumer. In short, I want to suspend the consumer when an exception happens due to an outage in downstream systems and resume the consumer when downstream systems are up again. As a reference I used this example from the Camel documentation: https://camel.apache.org/components/3.18.x/eips/resume-strategies.html#_pausable_consumers_api (coming from this test: https://github.com/apache/camel/blob/2c01082032346753cc6621ab4530b0969f12bac7/components/camel-kafka/src/test/java/org/apache/camel/component/kafka/integration/pause/KafkaPausableConsumerCircuitBreakerIT.java)
However, I noticed that every time the consumer is resumed it starts reading the messages from the earliest offset, and this causes a redelivery of all the messages stored in the partition; as far as I can tell it happens because KafkaConsumerListener#afterProcess invokes consumer.seekToBeginning.
I've created a reproducer here: https://github.com/lorenzobenvenuti/camel-kafka-pausable-bug
