title: java logging API, disable logging to standard output
body: <p>Using the standard java logging API (import java.util.logging.Logger), after the construction:</p>
  
  <pre><code>Logger l = Logger.getLogger("mylogger");
  </code></pre>
  
  <p>I am already able to log something. Since it has not a FileHandler, it doesn't write anything to disk. </p>
  
  <pre><code>l.severe("test with no handler");
  </code></pre>
  
  <p>It writes (some, not all) the log messages to output. 
  How can I disable this feature?
  thanks in advance
