Duration(java.lang.String lexicalRepresentation) throws StringIndexOutOfBoundsException when 'lexicalRepresentation' is a blank string ""

but according to the spec this case should throw java.lang.IllegalArgumentException

Test Program - Test1.java

import javax.xml.datatype.Duration;

public class Test1 {
 
    Test1() {}

    // main()
    public static void main(String[] argv) {
        Test1 test1 = new Test1();
        test1.checkDuration01();
    } //end main()
    
    // test for constructor Duration(java.lang.String lexicalRepresentation)
    // lexRepresentation - invalid blank string "" - should throw IllegalArgumentException
    private void checkDuration01() {
       String lexRepresentation = "" ;
       try{
           Duration duration01 = new Duration(lexRepresentation);
           System.out.println(" Expected IllegalArgumentException not thrown - checkDuration01() failed ");
       }catch( NullPointerException npe){
           System.out.println(" NPE thrown - checkDuration01() failed ");
       }catch( IllegalArgumentException iae){

       }catch( Exception e){
           System.out.println(" Exception thrown - checkDuration01() failed " );
       }
    }
