Otavio Rodolfo Piske resolved CAMEL-18760.
------------------------------------------
Fix Version/s: 4.2.0
Resolution: Fixed
As for 3.21.3, 3.22.0, 4.0.4 and 4.2.0, applications should use manual commit
for fine-grained control of the offsets and how Camel will behave when using
breakOnFirstError.
As such, this has been fixed by the fixes mentioned above.

> 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,
