  The following method of the class javax.xml.datatype.XMLGregorianCalendar
  
public static XMLGregorianCalendar fromGregorianCalendar(GregorianCalendar cal)

converts GregorianCalendar to XMLGregorianCalendar incorrectly. The following
fields are not processed as expected: ERA (if it is BC), HOUR_OF_DAY (treated as HOUR).

This bug affects new test in JCK 1.5 (not integrated yet)
    api/javax_xml/datatype/XMLGregorianCalendar/index.html#ConvertFrom[FromGregorianCalendar001]

The bug is found in jdk1.5.0/beta/b32.

To reproduce the bug compile and run the following code as shown
in the log below. Please set the property 'user.timezone' to 'UTC'
(this lets the code be simpler):
------------------------------------------ test.java
import javax.xml.datatype.XMLGregorianCalendar;
import java.util.GregorianCalendar;

class test {
    static final String FIELD_UNDEFINED = "FIELD_UNDEFINED";

    static String ifdef(int value) {
        return value == XMLGregorianCalendar.FIELD_UNDEFINED
                      ? FIELD_UNDEFINED
                      : (""+value);
    }

    static String calendar2Str(XMLGregorianCalendar calendar) {
        return "(" + calendar.getEonAndYear() + ", "
                   + ifdef(calendar.getMonth()) + ", "
                   + ifdef(calendar.getDay()) + ", "
                   + ifdef(calendar.getHour()) + ", "
                   + ifdef(calendar.getMinute()) + ", "
                   + ifdef(calendar.getSecond()) + ", "
            + (calendar.getMillisecond() == XMLGregorianCalendar.FIELD_UNDEFINED
                   ? FIELD_UNDEFINED
                   : (""+calendar.getMillisecond()/1000.0F)) + ", "
                   + ifdef(calendar.getTimezone())
            + ")";

    }

    public static void main(String [] args) {
        GregorianCalendar calendar1
            = new GregorianCalendar(1234, 0, 02, 14, 15, 57);
        calendar1.set(GregorianCalendar.ERA, GregorianCalendar.BC);
        calendar1.set(GregorianCalendar.MILLISECOND, 456);

        XMLGregorianCalendar returned
             = XMLGregorianCalendar.fromGregorianCalendar(calendar1);
        XMLGregorianCalendar expected
            = XMLGregorianCalendar.parse("-1234-01-02T14:15:57.456Z");
        if (!returned.equals(expected)) {
            System.out.println("returned " + calendar2Str(returned)
                             + ", expected " + calendar2Str(expected));
        } else {
            System.out.println("OK");
        }
    }
}
