    Programmatically creating timer no longer works

    David Roberts Apprentice

      Hi,

      When using Jbpm 3.2.3, I created a timer programmatically, which has always been working. This is my code to create a timer on the fly:

      public static void createTaskReminder(JbpmContext jbpmContext, TaskInstance taskInstance, Date dueDate, String repeat, String timerName) {
       try {
       // getting data from the context
       Token token = taskInstance.getToken();
      
       // creating the action
       Delegation timedDelegation = new Delegation("workflow.jbpm.TaskReminder");
       Action timedAction = new Action(timedDelegation);
      
       // creating the timer
       Timer timer = new Timer(token);
       timer.setName(timerName);
       timer.setAction(timedAction);
       timer.setRepeat(repeat);
       timer.setDueDate(dueDate);
       timer.setGraphElement(taskInstance.getTask().getTaskNode());
       timer.setTaskInstance(taskInstance);
      
       // scheduling the timer
       SchedulerService schedulerService = (SchedulerService) jbpmContext.getServices().getService(Services.SERVICENAME_SCHEDULER);
       schedulerService.createTimer(timer);
      
       }
       catch (Exception e) {
       e.printStackTrace();
       }
       }


      I am now using the latest 3.2.6 SNAPSHOT, but when closing the jbpmContext, I get the following exception:

      Any ideas what has changed, or what I am doing wrong?
