After looking at my watch list I clicked on "logout" and got this:
You have reached a page on Java.net that you are not authorized to see. Usually this happens when you are not logged in. If you feel you have reached this page in error please contact the webmaster
It seems Kenai tries to show the same page again, which obviously is for my eyes only. That is just wrong. Obviously in this situation the user has to be forwarded to the login page, instead to the same page.
