title: Log4J print empty line to logfile
body: <p>In java you could use System.out.println() to print a blank line but how does it work with log4j in a logfile?
  There I also want to have one or more blank lines inside the logfile.</p>
  
  <p>I already read the follwing:
  <a href="https://stackoverflow.com/questions/10531684/log4j-how-to-append-blank-line">log4j how to append blank line</a></p>
  
  <p>But this is not really helpful because with </p>
  
  <pre><code>logger.debug("\n");
  logger.debug("");
  </code></pre>
  
  <p>you do not print a message but other information like time and so on (the layout of the logger) are still stored inside the logfile. But I just want to have a total empty line.
  Can anyone help me please?</p>
