title: Using simple class name in java logging formatter
body: <p>I have a SimpleFormatter for logging in my application with the string<br> 
  <code>"%1$tF %1$tT %4$-7s %2$s %5$s%6$s%n"</code></p>
  
  <p>I would like to use the simple class name rather than the canonical name.  Is there a format option I can use with the 2$ field?  Or does this require writing a new Handler?</p>
  
  <p>For example, rather than <br>
  <code>2019-02-06 07:09:09 INFO    simplex.tools.SIMPLEXScheduler main Start</code></p>
  
  <p>I'd like to see <br><code>2019-02-06 07:09:09 INFO    SIMPLEXScheduler main Start</code></p>
