javax.swing.DefaultListModel.removeRange( fromIndex, toIndex) does not follow
specification. As specification says if fromIndex > toIndex
an IllegalArgumentException should be thrown but the implementation does
not do it.

(See JavaDoc comments)
public void removeRange(int fromIndex,
                        int toIndex)

     Deletes the components at the specified range of indexes. The removal is
     inclusive, so specifying a range of (1,5) removes the component at index 1 and
     the component at index 5, as well as all components in between.

     Throws an ArrayIndexOutOfBoundsException if the index was invalid. Throws an
     IllegalArgumentException if fromIndex > toIndex.


Here is the example demonstrating the bug:
------------------ Test.java -----------------
import java.awt.Label;
import javax.swing.DefaultListModel;

public class Test {
    public static void main(String[] argv) {
        DefaultListModel c = new DefaultListModel();
        Label object = new Label(" JCK TEST ");
        int size = 16;
        for(int i = 0; i < size; i++ ) {
            c.addElement( object);
        }
        try {
            c.removeRange( 3, 1);
            System.out.println("IllegalArgumentException has not been thrown");
            System.exit(0);
        } catch(IllegalArgumentException aioobe) {
        }
        System.out.println( "OKAY" );
    }
}
-------------- Output from the test -----------------
IllegalArgumentException has not been thrown
------------------------------------------------------
