             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:

Thanks,

lorenzo
