relative Link's href() explodes

[Vogel612]

Any time one calls Link#href() on a relative link (e.g. <a href="/users/login" />) a MalformedURLException will get thrown in AbstractResource#absoluteUrl()

Code reproducing the problem:

        HtmlDocument chatLoginRootPage = agent.get("http://stackexchange.com/users/chat-login");
        Links daLinks = chatLoginRootPage.links();
        daLinks.getAll().forEach(e -> LOGGER.info(e.href()));

assumptions:

 MechanizeAgent agent = new MechanizeAgent();
 //redirect strategies for agent enabled
 private static final Logger LOGGER = java.util.Logger.getLogger(MinimalWorkingExample.class.getName());

Root cause in stack-trace (calling code omitted):

Caused by: java.net.MalformedURLException: no protocol: /users/login?returnurl=%2fusers%2fchat-login
at java.net.URL.(URL.java:586)
at java.net.URL.(URL.java:483)
at java.net.URL.(URL.java:432)

Well, the problem here is with HtmlDocument isn't it? Either itself or its usage. Its .href() method only contains the path, query (and fragment?) elements of the URI, not its protocol or host.

On a sidenote, this is also happening with forms referencing relative URLs when they are submitted
