title: quartz scheduler: run on last day of the month
body: <p>I need to run a job on the last day of every month. i tried the following cron expression:</p>
  
  <pre><code>&lt;property name="cronExpression" value="0 0 3 L * * *" /&gt;
  </code></pre>
  
  <p>but got this error:</p>
  
  <pre><code>Caused by: java.lang.UnsupportedOperationException: Support for specifying both a day-of-week AND a day-of-month parameter is not implemented.
  </code></pre>
  
  <p>it doesnt like the <code>L</code>, but without using it, how can i run on the last day of the month?</p>
