(was: Hi Claus,

I have reproduced the issue. By removing Host from restConfiguration 
restConfiguration().port(8080); gives Host value Null . This can be checked in populateRests method of RouteBuilder class

##########################################################################################
        if (getRestConfigurations() != null) {
            for (Map.Entry<String, RestConfigurationDefinition> entry : getRestConfigurations().entrySet()) {
                RestConfiguration config = entry.getValue().asRestConfiguration(getContext());
                if ("".equals(entry.getKey())) {
                	if(entry.getValue().getHost()==null){
                	   throw new IllegalArgumentException("Host is  null in the provided endpoint");
                               
                	}
###########################################################################
 Please verify this,so that I can raise pull req
Regards
Ramu

> 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
