Rudder

When trying to start rudder-jetty with an oracle JDK jdk1.8.0_171-i586, I get in log file `/var/log/rudder/webapp/yyyy_MM_dd.jetty.log`

Running `service rudder-jetty supervise` leads to:

2018-05-24 17:36:16.266:INFO::main: Logging initialized @1136ms to org.eclipse.jetty.util.log.StdErrLog

Java HotSpot(TM) Server VM warning: You have loaded library /opt/rudder/jetty/lib/setuid/libsetuid-linux.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

It works as expected with OpenJDK 1.8.0_172.

Happens with rudder 4.3.
