> Please review this PR which addresses an edge case for > `GregorianCalendar.roll(int, int)` when the rolled amount would cause the > hour to remain the same as before the call. After this change, the expected > hour is returned. That is, rolling a full cycle for HOUR (12 hours) and > HOUR_OF_DAY (24 hours) should keep the hour the same as before the call. > > For example, a calendar with HOUR_OF_DAY == 15, > > > cal.roll(Calendar.HOUR_OF_DAY, 23); > cal.get(Calendar.HOUR_OF_DAY); // returns 14 > > > cal.roll(Calendar.HOUR_OF_DAY, 24); > // Incorrectly returns 16. A full cycle is expected to return the starting > hour (15) > cal.get(Calendar.HOUR_OF_DAY); > > > cal.roll(Calendar.HOUR_OF_DAY, 25); > cal.get(Calendar.HOUR_OF_DAY); // returns 16
