             Summary: camel validate yaml: an onException (or intercept, onCompletion) placed after the routes passes validation and fails at startup with a Java DSL message
                 Key: CAMEL-24846
                 URL: https://issues.apache.org/jira/browse/CAMEL-24846
             Project: Camel
          Issue Type: Improvement
          Components: camel-jbang, camel-yaml-dsl
            Reporter: Claus Ibsen


A YAML file with the error handler entry after the routes:

{code:yaml}
- route:
    from:
      uri: "timer:t?repeatCount=1"
      steps:
        - log: "hello"
- onException:
    exception:
      - java.lang.Exception
    handled:
      constant: "true"
    steps:
      - log: "handled"
{code}

validates ({{Validation success}}) and then fails at startup:

{code}
Error starting Camel: java.lang.IllegalArgumentException: onException must be defined before any routes in the RouteBuilder
{code}

"RouteBuilder" means nothing to a YAML author. The validator sees the order of the top-level entries and can say it before the run, in YAML words: "line 6: onException must come before the routes: move this entry above the first - route:". The runtime message can say the same when the source is YAML. The same applies to intercept, interceptFrom, interceptSendToEndpoint and onCompletion.

Found in the round-2 local-model benchmark on the camel-jbang-examples ladder (openapi-client): a validated file, a startup failure, and a round lost.
