>          Issue Type: Improvement
>          Components: camel-core
>    Affects Versions: 1.5.0
>            Reporter: Claus Ibsen

> The Registry only has lookup methods that return null if the bean was not found. Then we need to manually throw exception if the bean was expected.
> We need to expose mandatoryLookup methods that will do null check
> For instance:
> {code}
>             FTPClientConfig ftpClientConfig = this.getCamelContext().getRegistry().lookup(ref, FTPClientConfig.class);
>             if (ftpClientConfig == null) {
>                 throw new IllegalArgumentException("Damm can not find it");
>             }
> {code}
> Should just be:
> {code}
>             FTPClientConfig ftpClientConfig = this.getCamelContext().getRegistry().mandatoryLookup(ref, FTPClientConfig.class);
> {code}
