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

public boolean isValid()

throws NullPointerException for the valid XMLGregorianCalendar instance gMonth(FEBRUARY).

The method is declared to throw no exceptions and is expected to return true for gMonth(FEBRUARY).
So the sample (see below) should report "Passed: OK".

The bug is found in jdk1.5.0/beta2/b49 because the RI calls isValid() when parsing "--02--".

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

  api/javax_xml/datatype/XMLGregorianCalendar/index.html#Compare[Compare001]
  api/javax_xml/datatype/XMLGregorianCalendar/index.html#Compare[Equals001]
  api/javax_xml/datatype/XMLGregorianCalendar/index.html#GetSetCreate[CreateDate001]
  api/javax_xml/datatype/XMLGregorianCalendar/index.html#GetSetCreate[CreateDateTime001]
  api/javax_xml/datatype/XMLGregorianCalendar/index.html#GetSetCreate[CreateDateTime004]
  api/javax_xml/datatype/XMLGregorianCalendar/index.html#GetSetCreate[CreateDateTime006]

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

class test {
    public static void main(String [] args) {
        XMLGregorianCalendar gMonth = XMLGregorianCalendar.parse("2000-02");
        gMonth.setYear(null);
        boolean valid = gMonth.isValid();
        if (valid) {
            System.out.println("Passed: OK");
        } else {
            System.out.println("Failed: isValid returned false for gMonth(--02--)");
        }
    }
}
