             Summary: Issue using ThrottlingExceptionRoutePolicy with Kafka consumer
                 Key: CAMEL-18760
                 URL: https://issues.apache.org/jira/browse/CAMEL-18760
             Project: Camel
          Issue Type: Bug
            Reporter: Lorenzo Benvenuti


Hi,

while attempting to add the circuit breaker pattern to a route (see also CAMEL-18759), I tried to use {{ThrottlingExceptionRoutePolicy}} to suspend and resume the route when a specific exception is thrown. I noticed that regardless of the {{breakOnFirstError}} setting, the message causing the circuit to be opened is lost. If {{breakOnFirstError}} is {{true}}, logs are showing "Will seek consumer to offset -1 and start polling again", but when the circuit is closed the message is not consumed. I suspect that the consumer overwrites the offset when it's suspended. If I switch to manual commits, everything works as expected.

Reproducer here: https://github.com/lorenzobenvenuti/camel-kafka-break-on-first-error-bug

Thanks,

lorenzo
