      Description



      Name: erR10175 Date: 12/25/2003


       
        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");
          }
      }
