Rudder

Start command seems ok (ie config options from start.ini seems to be taken in to account): (linebreak added for readability)

Now I get:

OK, first comment was erroneous. It misses all JAVA options that we set in /opt/rudder/share/webapps/rudder-jetty.conf

Java options is not correctly pass to jetty start command.

The last problem is a bug in jetty: https://github.com/eclipse/jetty.project/issues/8152
