Hi,
I just tried to run Jetty 9 as non root users, using setuid feature
without success for binding low port numbers.
I enabled the module setuid in the start.ini and added
-Djava.library.path=/opt/jetty/lib/setuid
But I have the following stack trace when starting Jetty:
2015-06-09 16:27:27.211:WARN:oejx.XmlConfiguration:main: Config error

Those are the only references to this
error:http://jira.codehaus.org/browse/JETTY-1197

https://groups.google.com/forum/#!topic/dropwizard-user/aap2B_U_QPo
But they are either stopped or do not show the solution.
The source code I found for the setuid package is:
https://github.com/jetty-project/codehaus-jetty-project/blob/master/jetty-setuid/modules/java/src/main/java/org/mortbay/setuid/SetUID.java
Even though I cannot be sure this is the version I am using, given
this one is from a org.mortbay package, while the one Jetty 9 uses is
an Eclipse one.
I tried setting -Djetty.libsetuid.path in the java args (first
try-catch block), either adding the path to the $PATH variable or
setting -Djava.library.path (second try-catch block) and leaving it as
it is (third try-catch block). I got the same exception stack in all
the cases.
I cannot be sure if Jetty is either not finding the so file or not
being able to load it, given that, if I remove all the references to
the path (the cases I described latter), I still get the same error
message.
I use Java7 to run Jetty.
