        Description

        Name: erR10175 Date: 06/17/2004



         The following method of the class javax.xml.datatype.XMLGregorianCalendar

        public abstract XMLGregorianCalendar normalize()

        changes timezone of the calendar from undefined to UTC. Also, the method
        changes millisecond field from undefined to 0.

        The javadoc of the method refers to the W3C XML Schema Part 2, Section 3.2.7.3
        which reads:
        "
        A.Normalize P and Q. That is, if there is a timezone present, but it is not Z,
        convert it to Z using the addition operation defined in Adding durations
        to dateTimes
        "

        So in both cases (UTC and undefined) the method should leave
        the XMLGregorianCalendar instance unchanged.

        This bug affects new test in JCK 1.5
          api/javax_xml/datatype/XMLGregorianCalendar/index.html#Normalize[Normalize001]

        The bug is found in jdk15-b55 and jaxp13-b19 after the fix of following RI
        bug is integrated:

        5048932 XMLGregorianCalendar.normalize throws IllegalArgumentException

        To reproduce the bug compile and run the following code as shown in the log below.

                    XMLGregorianCalendar normalized = df.newXMLGregorianCalendar(normalizeValues[i])
                                                        .normalize();

                    }
                    if (orig.getMillisecond() != normalized.getMillisecond()) {
