-----------------------------------

             Summary: Warning logs when use OpenTelemetry with trace processors
                 Key: CAMEL-21919
                 URL: https://issues.apache.org/jira/browse/CAMEL-21919
             Project: Camel
          Issue Type: Improvement
          Components: camel-kafka
    Affects Versions: 4.10.3
            Reporter: Ruslan Hryn


The following warnings will appear during the application startup when using OpenTelemetry with a trace processor:

 
{code:java}
2025-03-31T15:35:24.627+03:00  WARN 91210 --- [demo] [           main] o.a.camel.impl.engine.DefaultChannel     : Interceptor: org.apache.camel.opentelemetry.OpenTelemetryTracingStrategy@210a26b at: Log[Hello World] does not return an AsyncProcessor instance. This causes the asynchronous routing engine to not work as optimal as possible. See more details at the InterceptStrategy javadoc. Camel will use a bridge to adapt the interceptor to the asynchronous routing engine, but its not the most optimal solution. Please consider changing your interceptor to comply. {code}
This issue can be easily reproduced by adding the following properties to a Spring Boot application:

 

 
{code:java}
camel:
  opentelemetry:
    enabled: true
    trace-processors: true {code}
Additionally, I have created a reproducer [here|https://github.com/RuslanHryn/camel-opentelemetry]
