>          Issue Type: Improvement
>          Components: camel-core
>    Affects Versions: 2.19.0

>
> If you forget to configure a host name then the rest producer fails with 
> different errors if you use http4, netty4-http, undertow etc.
> We should likely add some validation logic in the rest endpoint / rest 
> producer so it can detect this missing configuration and report this in the 
> same way.
> You can reproduce from this example by removing host at
> https://github.com/apache/camel/blob/master/examples/camel-example-rest-producer/src/main/java/sample/camel/RestRoute.java#L33
