=== API ===================================


  | Task task = jbpmServices.getTaskService().createTaskQuery().processDefinitionId("test-1").activityName("Inspection").uniqueResult();
  | Calendar cal = Calendar.getInstance();
  | BusinessCalendarImpl businessCalendar = new BusinessCalendarImpl();
  | Duration duration = new Duration("10 business days");
  | Date date = businessCalendar.add(cal.getTime(), duration);
  | task.setDuedate(date);
  | 

=== Stacktrace ==============================
anonymous wrote : 
  | Exception in thread "main" java.lang.NullPointerException
  | 	at org.jbpm.pvm.internal.cal.BusinessCalendarImpl.findDay(BusinessCalendarImpl.java:154)
  | 	at org.jbpm.pvm.internal.cal.BusinessCalendarImpl.findDayPart(BusinessCalendarImpl.java:160)

  | 	at eval.tester.tester.testTaskDueDate(tester.java:56)
  | 	at eval.tester.tester.main(tester.java:39)
  | 
=== Debug logs ==============================

Fails at this point:


  | protected Day findDay(Date date) {
  |     Calendar calendar = createCalendar();
  |     calendar.setTime(date);
  |     int weekDayIndex = calendar.get(Calendar.DAY_OF_WEEK);
  |     return days[weekDayIndex];
  |   }
  | 

=== Problem description =========================

BusinessCalendarImpl throws null pointer exception. Looking through the code it looks like its caused by the days[] being null. Am I using it correctly? Any help would be appreciated.
