> camel-micrometer - counter adds 1 when the increment or decrement option

> Key: CAMEL-26510
> URL: https://issues.apache.org/jira/browse/CAMEL-26510
> Project: Camel
> Issue Type: Bug
> Components: camel-micrometer
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 4.24.0
>
>
> The counter producer of camel-micrometer adds 1 when the {{increment}} or
> {{decrement}} option is set but gives no number.
> {{CounterProducer.doProcess}} evaluates both options (and the
> {{CamelMetricsCounterIncrement}} / {{CamelMetricsCounterDecrement}} headers).
> When both end up null, for example {{increment=$\{header.inc\}}} and the
> header is missing, it falls through to {{counter.increment()}} and counts 1
> for something that did not happen.
> camel-opentelemetry-metrics had the same bug (CAMEL-26195). Same fix here:
> when increment or decrement is configured but neither the options nor the
> headers give a number, fail the exchange and leave the counter unchanged.
> With neither option set, the counter still increments by 1 as documented.
> Upgrade-guide entry, since a route relying on the add-1 now fails.
