[Bug classpath/29149] New: GregorianCalendar problem with daylight-saving(?)

[twisti at complang dot tuwien dot ac dot at]

I found this code written by a student (stripped down to a simpler testcase):

        Date[] dates = new Date[3];
        GregorianCalendar gc = new GregorianCalendar(2005, 9, 30);

        for (int i = 0; i < 3; i++) {
            dates[i] = gc.getTime();
            gc.add(gc.DAY_OF_YEAR, 1);
        }

        for (int i = 0; i < dates.length; i++)
            System.out.println(dates[i]);

When running with RI, it prints:

$ /opt/jdk1.5.0_05/bin/java test
Sun Oct 30 00:00:00 CEST 2005
Mon Oct 31 00:00:00 CET 2005
Tue Nov 01 00:00:00 CET 2005

The same output with CACAO:

$ cacao test
