title: Spring 4.0.6 with quartz 1.8.6 : setCronExpression method is not exposed to CronTriggerBean class
body: <p>I am using spring version 4.0.6 and quartz with it, version 1.8.6. The problem is, when I try to use a configuration class instead of xml (with @Configuration annotation), I am not able to set the cron expression with the method </p>
  
  <blockquote>
    <p>CronTriggerBean ctBean = new CronTriggerBean();
    ctBean.setCronExpression("0 35 15 ? * MON *");</p>
  </blockquote>
  
  <p>Please tell me if there is a version compatibility issue.</p>
  
  <p>The exact error is this:</p>
  
  <blockquote>
    <p>The method setCronExpression(String) is undefined for the type CronTriggerBean</p>
