There seems to be an inconsistancy between GregorianCalendar.add
(Calendar.DAY_OF_YEAR, int) and the resulting GregorianCalendar.get
(Calendar.DAY_OF_YEAR)) for the default change over year 1582. In this year,
adding one day to October 4, the 277th day of the year, increments the calendar
to October 15 as expected. However, get(Calendar.DAY_OF_YEAR)) for October 15
returns 288, 11 days later. Is this the proper behavior? I would expect that
adding one day would increment the DAY_OF_YEAR by one as well.

This code:

    GregorianCalendar testCal = (GregorianCalendar)Calendar.getInstance();
    testCal.set(1582, Calendar.JANUARY, 1);
    while(testCal.get(Calendar.YEAR)==1582){
      System.out.println(testCal.getTime());
      System.out.println(testCal.get(Calendar.DAY_OF_YEAR));
      testCal.add(Calendar.DAY_OF_YEAR, 1);
    }

will produce the following output:
