Scheduled Service in CQ5

Cron or Quartz like behaviour in CQ5 comes out of the box. See more examples. I have seen the annotation as comments, which I think is a bad style.

import org.apache.felix.scr.annotations.Component; 
import org.apache.felix.scr.annotations.Property; 
import org.apache.felix.scr.annotations.Service; 
import org.slf4j.Logger; import org.slf4j.LoggerFactory;  

@Component @Service @Property(name="scheduler.expression", value = "0 * * * * ?") 
public class ScheduledJob implements Runnable {      
  private static final Logger LOGGER = LoggerFactory.getLogger(ScheduledJob.class);      

  public void run() {         
    // your code goes here ...     
  } 
}
