JMenuItem and JTextField doesn't look right after upgrading to Java 8

Question

I just upgraded to JDK 8u25
I have a legacy Swing application, which makes use of JMenuItem and JTextField
I realize, after upgrading, there is a bolder grey vertical border at the left side of JMenuItem and JTextField
JMenuItem
JTextField
This only happen, if I were using look n feel com.sun.java.swing.plaf.windows.WindowsLookAndFeel
Before that, I never have such problem. Anyone know is there any workaround for such problem?
Here's the code example to demonstrate the problem.
package javaapplication5;
* @author yccheok
public class NewJFrame extends javax.swing.JFrame {
     * Creates new form NewJFrame
    public NewJFrame() {
        initComponents();
     * This method is called from within the constructor to initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is always

The site looks OK -- actually quite impressive for what appears to be a from-scratch design.
In Opera 10 under Snow Leopard 10.6.1, the design doesn't start to explode until the horizontally scrolling marquee comes across. I would strongly recommend just removing that marquee; it is an extremely outdated element of web design. If you do that, the design shouldn't blow up on you in other browsers.
