Sailpoint Identity IQ CertificationAutomaticClosing Rule

We have seen many time to send the Expiry Notification , when the Access Review is Expired , ie no action is taken CertificationAutomaticClosingRule can be used to send the notification , here is the sample code for using this Rule. 

  import sailpoint.object.Identity;
  import sailpoint.object.EmailOptions;
  import sailpoint.object.EmailTemplate;  
  import sailpoint.object.Certification;
  import org.apache.commons.logging.Log;
  import sailpoint.object.SignOffHistory;
  import org.apache.commons.logging.LogFactory;

  System.out.println("Entering Certification Auto closing rule.");

  List toAddresses = Arrays.asList("");

  List certifiers = certification.getCertifiers();
  Identity certifier = context.getObjectByName(Identity.class,certifiers.get(0).toString());
  System.out.println("certifier : " + certifier);

  if(null != certifier){
    toAddresses = Arrays.asList(certifier.getEmail());
    System.out.println("toAddresses : " + toAddresses);
  }

  String tplName = "Certification Expired Notification";
  EmailTemplate template = context.getObjectByName(EmailTemplate.class, tplName);
  if (null == template) {  
    System.out.println("Could not find email template [ " + tplName + "]");
    return;
  }

  Map args = new HashMap();  
  args.put("certification", certification);
  args.put("ownerName", certifier.getDisplayName());

  System.out.println("certification : " + certification);
  System.out.println("ownerName : " + certifier.getDisplayName());

  certification.addSignOffHistory((Identity)context.getObjectByName(Identity.class, "spadmin"));
  
  //Send Notifciation of Expiry
  
  System.out.println("Exiting Certification Auto closing rule");
  return ;
