If you are going to use java.util.logging with chef, make jetty 9 use it too

[joakime]

It appears that you are configuring Jetty 9 for java.util.logging.

If that is the case, then either config:

1. Jetty to use Slf4jLog internally (using slf4j's java.util.logging bridge)
2. Jetty to use JavaUtilLog internally (using your own configured java.util.logging handler to manage output)

In either case, the use of --module=logging should be discouraged, as that will simply redirect System.out and System.err to a file ${jetty.base}/logs/stderrlog.log
