SpringLayout fails to resize

Question

re: Java Tutorial, How to Use SpringLayout
http://java.sun.com/docs/books/tutorial/uiswing/layout/spring.html
run SpringDemo3.java, given as an example on this page.
resize (expand) the frame by grabbing a border.
this works.
now attempt to resize (contract) the frame the same way.
this does not work.
why?
the code to create and lay out the frame is given below:
private static void createAndShowGUI() {
    //Make sure we have nice window decorations.
    JFrame.setDefaultLookAndFeelDecorated(true);
    //Create and set up the window.
    JFrame frame = new JFrame("SpringDemo3");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    //Set up the content pane.
    Container contentPane = frame.getContentPane();
    SpringLayout layout = new SpringLayout();
    contentPane.setLayout(layout);
    //Create and add the components.
    JLabel label = new JLabel("Label: ");
    JTextField textField = new JTextField("Text field", 15);
    contentPane.add(label);
    contentPane.add(textField);
    //Adjust constraints for the label so it's at (5,5).
    layout.putConstraint(SpringLayout.WEST, label,
                         5,
                         SpringLayout.WEST, contentPane);
    layout.putConstraint(SpringLayout.NORTH, label,
                         5,
                         SpringLayout.NORTH, contentPane);
    //Adjust constraints for the text field so it's at
    //(<label's right edge> + 5, 5).
    layout.putConstraint(SpringLayout.WEST, textField,
                         5,
                         SpringLayout.EAST, label);
    layout.putConstraint(SpringLayout.NORTH, textField,
                         5,
                         SpringLayout.NORTH, contentPane);
    //Adjust constraints for the content pane: Its right
    //edge should be 5 pixels beyond the text field's right
    //edge, and its bottom edge should be 5 pixels beyond
    //the bottom edge of the tallest component (which we'll
    //assume is textField).
    layout.putConstraint(SpringLayout.EAST, contentPane,
                         5,
                         SpringLayout.EAST, textField);
    layout.putConstraint(SpringLayout.SOUTH, contentPane,
                         5,
                         SpringLayout.SOUTH, textField);
    //Display the window.
    frame.pack();
    frame.setVisible(true);
}
