Windows support of native GSS-API in Java 6

From http://java.sun.com/developer/technicalArticles/J2SE/security/#3:

Note: These two system properties are ignored when applications run on operating systems that do not yet support this feature, for example, MS Windows.

That document is from 2006, so things could have changed but I've not found a definitive answer.

I would like to know if the latest release of Sun Java 6 for Windows support native GSS today (to get the TGT without tinkering with the registry).

Nope
