Changung the UIDefaults property 'ScrollBar.width' does not affect.
The problem appears only on windows L&F.
Following is a code that demonstrates the problem exactly.
(you can copy-paste it to a file, compile and run it immediately):


import java.awt.*;
import javax.swing.*;
import java.awt.event.*;

public class ScrollBarDemo
{
 public static void main(String[] str)
 {
  ScrollBarDemo s = new ScrollBarDemo();
 }


 public ScrollBarDemo()
 {
  // When commenting this try-catch clause, it works...
  try
  {
    UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
  }
  catch (Exception exc)
  {
   System.err.println("Error loading L&F: " + exc);
   System.exit(0);
  }

  int sb_w = UIManager.getInt("ScrollBar.width");
  System.out.println(sb_w); // prints '0' on Windows L&F

  UIManager.put("ScrollBar.width", new Integer(32));

  sb_w = UIManager.getInt("ScrollBar.width");
  System.out.println(sb_w);

  JFrame frame = new JFrame();

  frame.addWindowListener(new WindowAdapter()
   {
    public void windowClosing(WindowEvent e)
    {
     System.exit(0);
    }
   });

  JPanel panel = new JPanel();

  JPanel p1 = new JPanel(new BorderLayout());

  JComboBox cb = new JComboBox(new String[] {"a","b","c","d","e","f"});
  cb.setMaximumRowCount(5);
  p1.add(cb, BorderLayout.NORTH);

  JScrollPane sp = new JScrollPane(p1);

  sp.setPreferredSize(new Dimension(200,200));

  sp.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
  sp.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);

  panel.add(sp);

  frame.setContentPane(panel);
  frame.pack();
  frame.setVisible(true);
 }
}
