---------------------------------
Fix Version/s: 4.23.0
Resolution: Fixed
> PropertyBindingException from camel-main configuration hides the cause: the
> message should carry the root cause

> Key: CAMEL-24836
> URL: https://issues.apache.org/jira/browse/CAMEL-24836
> Project: Camel
> Issue Type: Improvement
> Components: camel-core
> Reporter: Claus Ibsen
> Priority: Major
> Fix For: 4.23.0
>
>
> Starting with
> {code}
> camel.component.rest-openapi.host=http://localhost:8080/api
> {code}
> fails with
> {code}
> Error starting Camel: org.apache.camel.PropertyBindingException: Error
> binding property
> (camel.component.rest-openapi.host=http://localhost:8080/api) with name: host
> on bean:
> org.apache.camel.component.rest.openapi.RestOpenApiComponent@56826a75 with
> value: http://localhost:8080/api
> {code}
> The reason is two {{Caused by}} lines down the stack trace:
> {code}
> Caused by: java.lang.IllegalArgumentException: host must be an absolute URI
> (e.g. http://api.example.com), given: `http://localhost:8080/api`
> {code}
> The first line is what a person reads, what an IDE shows, and what a coding
> agent gets when the log is trimmed; it says the binding failed and nothing
> about why. {{PropertyBindingException.getMessage()}} (or the main support's
> error reporting) should append the message of the root cause when there is
> one: "... with value: http://localhost:8080/api: host must be an absolute URI
> (e.g. http://api.example.com)".
> Found in the round-2 local-model benchmark on the camel-jbang-examples
> ladder: the model set the host with a path, read the first line, and could
> only guess. The same applies to every setter that throws an
> IllegalArgumentException with a good message.
