The main freebsd.org website port search is returning old data. I just did a search for "jetty" and got results which show the old version of the port. portsnap on a machine shows a much newer one. At the bottom of the results page you can see that the DB for the web search is out of date: "Last database update: 2012-11-11 10:45:48 UTC" How-To-Repeat: http://www.freebsd.org/cgi/ports.cgi?query=jetty&stype=all
This was due to the move from cvs to svn, and was fixed quite some time ago
