title: How to get the next LocalDateTime from an initial LocalDateTime and a cron expression?
body: <p>I have an initial date and a cron expression. How could I find the next date satisfying this cron expression ?.</p>
  
  <pre><code>    String cronExpresion = "* * * * * *"
      LocalDateTime initial = LocalDateTime.now()
      LocalDateTime next = ?
  </code></pre>
  
  <p>I tried CronSequenceGenerator and its <em>next()</em> method but it uses java.util.Date and I would prefer not to convert LocalDateTime to Date and vice versa. Plus, I've got different result (time between the 2 dates) from several run with a cron like 'every 10 secondes' ...</p>
  
  <p>Any idea ? lib ?</p>
