  The following methods of the class javax.xml.datatype.Duration
  
public Duration multiply(int factor)
public final Duration multiply(BigDecimal factor)
 
does not multiply seconds in the duration.
 
The documentation of the methods reads:

"Computes a new duration whose value is factor times longer than the value
of this duration."

So for example, the duration "PT1M1S" and the factor 2 must produce "PT2M2S",
but both methods return "PT2M1S".

This bug affects new test in JCK 1.5 (not yet integrated)
   api/javax_xml/datatype/Duration/index.html#DurationTests[Multiply001]
   api/javax_xml/datatype/Duration/index.html#DurationTests[Multiply002]

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(\"PT1M1S\").multiply(2) returns "
            + new Duration("PT1M1S").multiply(2)
            + ", expected PT2M2S");
        System.out.println("new Duration(\"PT1M1S\")"
            +".multiply(new BigDecimal(\"2\")) returns "
            + new Duration("PT1M1S").multiply(new BigDecimal("2"))
            + ", expected PT2M2S");
    }
}
