---------------------------------
Fix Version/s: 4.23.0
Resolution: Fixed
> 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
> Priority: Major
> Fix For: 4.23.0
>
>
> 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.
