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

public static int compare(Duration lhs, Duration rhs)

throws IllegalArgumentException if the first duration is negative and
has non-zero day, hour, minute or second field specified (e.g. '-P1D',
'-P1DT1H')

Javadoc of the method does not specify any case when
IllegalArgumentException may be thrown, so it is a bug.

This bug affects new tests in JCK 1.5 (not integrated yet)
    api/javax_xml/datatype/Duration/index.html#Add[Add001]
    api/javax_xml/datatype/Duration/index.html#Ctor[Ctor003]
    api/javax_xml/datatype/Duration/index.html#Negate[Negate001]
    api/javax_xml/datatype/Duration/index.html#Subtract[Subtract001]

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:
------------------------------------------ test.java
import javax.xml.datatype.Duration;

public class test {
    public static void main(String [] args) {
        Duration d1 = new Duration("-P1D");
        Duration d2 = new Duration("P1Y");
        Duration.compare(d1,d2);
        System.out.println("OK");
    }
}
