Pasquale Congiusti commented on CAMEL-22612:
--------------------------------------------
I can't reproduce this problem. I've tried with the dependencies you've
suggested but in my case everything works as expected. However I think this is
a runtime problem due to a clash in bean creations. It's clear that you may
have additional configurations that are creating the Spring
`tracingAwareMeterObservationHandler` versus Camel
`tracingAwareMeterObservationHandler`. In theory such a clash should not
happen, but I guess it depends on the different dependencies that may be
available in a given project. The most immediate workaround is to instruct
Spring not to use the `TracingAndMetricsObservationHandlerConfiguration`
configuration. I think there may be some properties to set it up.
In the while I am preparing an alternative approach to let coexist the Spring
configuration with our configuration without having any potential clash.
Stay tuned.

> Key: CAMEL-22612
> URL: https://issues.apache.org/jira/browse/CAMEL-22612
> Project: Camel
> Issue Type: Bug
> Components: camel-spring-boot-starters
> Affects Versions: 4.15.0
> Environment: Apache Camel 4.15.0, including camel-observation-starter.
> Spring Boot 3.5.7, including spring-boot-actuator-autoconfigure.
> Reporter: Mikołaj Nowak
> Assignee: Pasquale Congiusti
> Priority: Major
> Fix For: 4.16.0
>
>
> With Apache Camel 4.15.0 and Spring Boot 3.5.7, camel-observation-starter
> causes application startup error:
> The bean 'tracingAwareMeterObservationHandler', defined in class path
> resource
> [org/apache/camel/observation/starter/ObservationAutoConfiguration.class],
> could not be registered. A bean with that name has already been defined in
> class path resource
> [org/springframework/boot/actuate/autoconfigure/observation/ObservationAutoConfiguration$MeterObservationHandlerConfiguration$TracingAndMetricsObservationHandlerConfiguration.class]
> and overriding is disabled.
>
> Setting camel.observation.enabled to false resolves the startup error, but
> then tracing does not work for Camel routes. The issue might be related to
> CAMEL-22349.
>
> As a temporary workaround, I downgraded Camel to 4.14.0. The issue does not
> occur in that version.
