When a HttpURLConnection encounters a redirect, it attempts to parse the
redirect URL.  This may be a relative URL, however it is parsed as an
absolute URL.  Consequently, a relative URL appearing in the redirect
header will result in a Malformed URLException rather than the correct
redirection behavior.

The underlying bug is in the class

	sun.net.www.protocol.http.HttpURLConnection

in the method

	followRedirect()

in the statment

	locUrl = new URL(loc);

Which should be using the two-argument version of the URL constructor.
