  Method javax.xml.datatype.Duration.multiply(int factor) throws
IllegalArgumentException if the factor is negative.

The documentation of the method does not explicitly forbid
to use negative values for the argument 'factor'. Besides
IllegalArgumentException is not specified to be throwable by the
method. So the expected befaviour is to change the sign of the
duration object and multiply it with the absolute value of
the factor.

This bug affects new test in JCK 1.5 (not yet integrated)
   api/javax_xml/datatype/Duration/index.html#DurationTests[Multiply001]

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 d = new Duration("-PT1M");
        d.multiply(-1);
    }
}
