title: How to define an additional Java log level?
body: <p>The <a href="http://docs.oracle.com/javase/7/docs/api/java/util/logging/Level.html" rel="nofollow noreferrer">standard Java logging</a> defines the following log levels:</p>
  <ul>
  <li>SEVERE (highest)</li>
  <li>WARNING</li>
  <li>INFO</li>
  <li>CONFIG</li>
  <li>FINE</li>
  <li>FINER</li>
  <li>FINEST</li>
  </ul>
  <p>This is incompatible to <a href="https://www.rfc-editor.org/rfc/rfc5424" rel="nofollow noreferrer">RFC 5424</a>, because it lacks a NOTICE level between INFO and WARNING. Java lacks some additional log levels (error, critical, alert and emergency) but NOTICE is the one which hurts me.</p>
  <p>Is there any way to extend the list of possible log levels in order to add the missing NOTICE level? Or is it necessary to rewrite the whole logging?</p>
