The packaged jetty-setuid.xml file uses the id "Server" for its Configure element, causing a ClassCastException

Ido,

The problem appears to be that when using "/etc/init.d/jetty start", the command line produced is:

"/usr/lib/jvm/jdk1.7/bin/java -Djetty.home=/opt/jetty -Djava.io.tmpdir=/tmp -jar /opt/jetty/start.jar --pre=etc/jetty-logging.xml --daemon"

This puts etc/jetty-logging.xml first onto the command line, which creates an instance of Server that is org.eclipse.jetty.server.Server. Thus, when etc/jetty-setuid.xml is executed, it cannot cast that to be org.mortbay.jetty.setuid.SetUIDServer.

I think the solution for you is to insert "-pre=etc/jetty-setuid.xml" into /opt/jetty/jetty.conf file before the "-pre=etc/jetty-logging.xml" (and make sure you take etc/jetty-setuid.xml out of your start.ini).

Alternatively, you could remove the "--pre=etc/jetty-logging.xml" from the init.d script, and instead add etc/jetty-logging.xml after etc/jetty-setuid.xml.

I will document this on the wiki.

Note: in previous releases where the id was incorrectly "org.eclipse.jetty.server.Server", the jetty-setuid.xml file would have been incorrectly creating a second Server instance and applying the setuid configuration to it. Thus I believe the jetty server instance created by the etc/jetty-logging.xml file with id Server would have in fact continued to run as root.

PS I also created this bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=390160 as I received warnings about the poor quality of the jetty debian bundles when I tried to install them. We should improve them.
