Latest rewrite rules (see helpdesk ticket reference) resulted into all requests to labs.jboss.org/downloading/?... that are not handled by preceeding rewrite rules are redirected to the Project Matrix instead to the new location of the intended download.

E.g. http://labs.jboss.com/downloading/?http://sourceforge.net/project/showfiles.php?group_id=22866&package_id=16942&projectId=jbossas&release_id=305380 should be redirected to http://sourceforge.net/project/showfiles.php?group_id=22866&package_id=16942&projectId=jbossas&release_id=305380 but it ends into http://www.jboss.org/projects/matrix
