The methods java.util.Calendar.setMinimalDaysInFirstWeek() and
java.util.Calendar.setFirstDayOfWeek() affect the calculation of the
WEEK_OF_MONTH and WEEK_OF_YEAR fields. However,
setting these parameters of a calendar doesn't cause those
fields to be invalidated.

Sample source:

import java.util.*;

public class TestWOY {
  public static void main(String[] argv) {
    Calendar cal = new GregorianCalendar();

    cal.set(Calendar.YEAR, 1999);
    cal.set(Calendar.MONTH, Calendar.MAY);
    cal.set(Calendar.DATE, 10);
    cal.set(Calendar.HOUR_OF_DAY, 9);
    cal.set(Calendar.MINUTE, 0);
    cal.set(Calendar.SECOND, 0);
    cal.set(Calendar.MILLISECOND, 0);

    int WOY1 = cal.get(Calendar.WEEK_OF_YEAR);

    cal.setMinimalDaysInFirstWeek(4);
    cal.setFirstDayOfWeek(Calendar.MONDAY);

    int WOY2 = cal.get(Calendar.WEEK_OF_YEAR);

    cal.clear(Calendar.WEEK_OF_YEAR);

    int WOY3 = cal.get(Calendar.WEEK_OF_YEAR);

    System.out.println("WOY1 = " + WOY1);
    System.out.println("WOY2 = " + WOY2);
    System.out.println("WOY3 = " + WOY3);
  }
}


Expected output:
WOY1 = 20
WOY2 = 19
WOY3 = 19

Actual output:
WOY1 = 20
WOY2 = 20
WOY3 = 19
