AdviceWithRouteBuilder replaceFromWith and microprofile-metrics conflict

[jwwallin]

I'm trying to write tests for a quartz triggered route by replacing the original from-endpoint using AdviceWithRouteBuilder.adviceWith(camelContext, "scheduler-daily", advisor -> {advisor.replaceFromWith("direct:scheduler-daily");}).

When I run the test, I get this error:

org.apache.camel.FailedToCreateRouteException: Failed to create route scheduler-daily: Route(scheduler-daily)[From[direct:scheduler-daily] -> [Log[... because of A metric with metricID MetricID{name='camel.route.exchanges.inflight.count', tags=[camelContext="camel-1",routeId="scheduler-daily"]} already exists
        at TimerRouteTest.mockRouteEndpoints(TimerRouteTest.java:53)
Caused by: java.lang.IllegalArgumentException: A metric with metricID MetricID{name='camel.route.exchanges.inflight.count', tags=[camelContext="camel-1",routeId="scheduler-daily"]} already exists
        at TimerRouteTest.mockRouteEndpoints(TimerRouteTest.java:53)

Am I missing something or is there a bug in the way the replaceFromWith(...) interacts (or maybe doesn't interact) with camel-quarkus-microprofile-metrics?

Log before the error looks like this:

It's probably a bug in the camel-microprofile-metrics component. Looks like adviceWith or replaceFrom results in an attempt to register a metric that already exists.

You could try disabling the route metrics by adding the following to application.properties:

quarkus.camel.metrics.enable-route-policy=false

[jwwallin]

I disabled the route metrics as suggested and it works fine.

I added a workaround to fix the issue for the 1.2.0 release.

It'll be fixed properly when the project upgrades to Camel 3.6.0.
