------------------------------------

I have paper-printed calendar with weeks numbering for European standard (where min days is 4) - and the week of 1st Jan is marked as 53rd, but not 1st.

Here is what JDK states:

        Locale aLocale = new Locale("de", "DE");
        Calendar calendar = Calendar.getInstance(aLocale);
        calendar.setTimeZone(TimeZone.getTimeZone("GMT"));
        calendar.clear();
        calendar.set(Calendar.YEAR, 2010);
        calendar.set(Calendar.MONTH, Calendar.JANUARY);
        calendar.set(Calendar.DATE, 1);
        
        System.out.println(aLocale.getDisplayLanguage(Locale.US));
        
        System.out.println(calendar.get(Calendar.WEEK_OF_YEAR));
        System.out.println(calendar.getTime());
        calendar.add(Calendar.DATE, -1);
        System.out.println(calendar.get(Calendar.WEEK_OF_YEAR));
        System.out.println(calendar.getTime());

> Week numbering in calendar doesn't match:
> Calendar is opened for december, 2009. First two days of next year january belong to 53 week of 2009, however week starting from 3rd january is marked as 1st week of 2010 year, should be 2nd. When calendar is opened for january, 2010 then week starting from 3rd january is marked as 2nd week of 2010! Week numbering must match.
