Parameters passed to standalone.sh should also be printed on startup (like JAVA_OPTS).
Actually I think something like the output of `ps aux | grep "org.jboss.as.standalone"` should also be printed, when jboss starts.

Not printing them causes confusion between what is printed and what is actually applied.

If for example someone runs this: `standalone.sh -Djboss.socket.binding.port-offset=100` and at the same time `-Djboss.socket.binding.port-offset=0` exists in JAVA_OPTS, then the latter will be printed but the first will be used.

Someone might argue about setting only JAVA_OPTS before running standalone.sh.

The reason I avoid setting JAVA_OPTS is that if I set them before running standalone.sh, then the default Wildfly opts (-Djava.net.preferIPv4Stack=true" -Djboss.modules.system.pkgs=$JBOSS_MODULES_SYSTEM_PKGS -Djava.awt.headless=true") are never used, which causes other problems. This could be a bug byitself, but for now I consider it as expected behaviour.

So the most clean approach that I see for setting options in a single place (both with -D and custom flags (e.g. -b)) is appending them as params to standalone.sh (e.g. inside a wrapper script myapp-run.sh).
It should be possible however to be able to see them being printed somewhere.
