   The method the class javax.xml.datatype.XMLGregorianCalendar

public void add(Duration duration)

incorrectly modifies the XMLGregorianCalendar representation of
the date "2000-01-01T00:00:00Z" when one day is subtracted from it. The result of
the method call is "1999-11-30T00:00:00Z", but it should be "1999-12-31T00:00:00Z".

The bug affects the following new JCK-15 beta2 test:

  api/javax_xml/datatype/XMLGregorianCalendar/index.html#Add[Add003]

The bug is found in jdk1.5.0/beta2/b44. The test is in KFL with the RI bug

4972801 XMLGregorianCalendar.parse cannot parse long years

To reproduce the bug compile and run the following code as shown in the log below.
------------------------------------------ test.java
import javax.xml.datatype.XMLGregorianCalendar;
import javax.xml.datatype.Duration;

class test {

    public static void main(String [] args) {
        XMLGregorianCalendar calendar
            = XMLGregorianCalendar.parse("2000-01-01T00:00:00Z");
        XMLGregorianCalendar expected
            = XMLGregorianCalendar.parse("1999-12-31T00:00:00Z");
        calendar.add(new Duration("-P1D"));
        if (!calendar.equals(expected)) {
            System.out.println("returned: " + calendar.toXMLFormat());
            System.out.println("expected: " + expected.toXMLFormat());
        } else {
            System.out.println("OK");
        }
    }
}
