  The method javax.xml.datatype.Duration.multiply(BigDecimal factor)
does not throw IllegalStateException if 1 year is multiplied by 0.5.
 
The documentation of the method reads:

"An IllegalStateException is thrown If the operation produces fraction
in the months or year field. For example if you multiple one month or
year by 0.5."

So, even if 1 year * 0.5 is exactly 6 months, the method must throw
IllegalStateException, to conform to the doc, because 0.5 years has
a fraction part.

This bug affects new test in JCK 1.5 (not yet integrated)
   api/javax_xml/datatype/Duration/index.html#DurationTests[Multiply003]

The bug is found in jdk1.5.0/beta/b25.

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


public class test {

    public static void main(String [] args) {
        System.out.println("new Duration(\"P1Y\")"
            +".multiply(new BigDecimal(\"0.5\")) returns "
            + new Duration("P1Y").multiply(new BigDecimal("0.5"))
            + ", expected IllegalStateException");
    }
}
----------------------------------------------------

$javac test.java && java -cp . -showversion test
