Crawl stops on non-www URLs

What is the current behavior? If I specify a domain like eg. "http://www.domainname.com/" but the preferred domain settings on the server are without "www." then the crawling process stops.

The REVERSE is also valid unfortunately if I specify a DOMAIN that has "www" but I do not specify it eg. "http://domainname.com/" the crawling also STOPS.

If the current behavior is a bug, please provide the steps to reproduce

What is the expected behavior? Normally I expect it to recognize the domain name without "www"

What is the motivation / use case for changing the behavior?
