Strange problem with Calendar comparison
While writing databinding tests for java.util.Calendar type, I have hit a
strange problem with comparing Calendar objects. The problem occurs only
when using binding.ws to invoke the service method. Even in the problematic
case, expected.toString() and actual.toString() are equal but
expected.equals(actual) returns false!! Here is an excerpt from the
FailureTrace:
expected:<java.util.GregorianCalendar[time=1212745401890,areFieldsSet=true,areAllFieldsSet=true,lenient=true,zone=sun.util.calendar.ZoneInfo[id="GMT+05:30",offset=19800000,dstSavings=0,useDaylight=false,transitions=0,lastRule=null],firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2008,MONTH=5,WEEK_OF_YEAR=23,WEEK_OF_MONTH=1,DAY_OF_MONTH=6,DAY_OF_YEAR=158,DAY_OF_WEEK=6,DAY_OF_WEEK_IN_MONTH=1,AM_PM=1,HOUR=3,HOUR_OF_DAY=15,MINUTE=13,SECOND=21,MILLISECOND=890,ZONE_OFFSET=19800000,DST_OFFSET=0]>
but
was:<java.util.GregorianCalendar[time=1212745401890,areFieldsSet=true,areAllFieldsSet=true,lenient=true,zone=sun.util.calendar.ZoneInfo[id="GMT+05:30",offset=19800000,dstSavings=0,useDaylight=false,transitions=0,lastRule=null],firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2008,MONTH=5,WEEK_OF_YEAR=23,WEEK_OF_MONTH=1,DAY_OF_MONTH=6,DAY_OF_YEAR=158,DAY_OF_WEEK=6,DAY_OF_WEEK_IN_MONTH=1,AM_PM=1,HOUR=3,HOUR_OF_DAY=15,MINUTE=13,SECOND=21,MILLISECOND=890,ZONE_OFFSET=19800000,DST_OFFSET=0]>
Any ideas what could be wrong?

Found the problem... The Calendar object returned over binding.ws,
GregorianCalendar object, has a gregorianCutover field set to
-9223372036854775808 (== Long.MIN_VALUE). Whereas the one returned by
Calendar.getInstance() has the field set to
GregorianCalendar.DEFAULT_GREGORIAN_CUTOVER = -12219292800000L. Here is
what javadoc for GregorianCalendar.setGregorianChange() says: "To obtain a
pure Julian calendar, set the change date to Date(Long.MAX_VALUE). To
obtain a pure Gregorian calendar,set the change date to
Date(Long.MIN_VALUE)."
