  The following method of the class javax.xml.datatype.XMLGregorianCalendar
  
public final void setTimeZone(TimeZone value)

does not throw NullPointerException if the value is null but the documentation
of the method reads:

"Throws: NullPointerException - if the TimeZone is null"

This bug affects new test in JCK 1.5 (not integrated yet)
   api/javax_xml/datatype/XMLGregorianCalendar/index.html#XMLGregorianCalendar[SetTimeZone003]

The bug is found in jdk1.5.0/beta/b28.

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 calendar = new XMLGregorianCalendar();
        try {
            calendar.setTimeZone(null);
            System.out.println("setTimeZone(null) does not throw NullPointerException");
        } catch (NullPointerException e) {
            System.out.println("OK");
        }
    }
}
