Rudder

RESOLUTION NOTE: the provided patch use the OpenJDK boot parameter "CrashOnOutOfMemoryError" that is only available since OpenJDK 1.8.0_92. You should really use a more recent OpenJDL than that for performance and security reasons, but if you are stuck with a 6 years old runtime, you can modify the file /opt/rudder/etc/rudder-jetty.conf and remove it.

In #14281 we added an handler for fatal exception so that they force rudder to stop (because from that point, rudder is broken in unknown way).

But now, rudder doesn't stop on them:
