adding border to JSlider using Nimbus

I create a vertical JSlider with ticks and labels painted.
Its width is x pixels (x depends on the font, etc.)

I then add a border using:
  mySlider.setBorder( BorderFactory.createLineBorder( Color.black,
10 ) );

With Metal L&F, the internal part ofstays the same width, with
a 10-pixel wide border around it; the component's width is now
(x+20) pixels. This is what I would expect - the component
wants to be x pixels wide (to display the slider and the scales)
plus 10 pixelsl on each side for the border.

Using Nimbus, however, the component stays the same width,
with the border inside it, clipping 10 pixels off each edge.

How can I add the border correctly using Nimbus?

Here's the code:

import java.awt.Color;
import java.awt.FlowLayout;

import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JSlider;
import javax.swing.UIManager;
import javax.swing.border.Border;

public class Slide extends JPanel {
   public Slide() {
      try {
         UIManager.setLookAndFeel(
           "com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel" );
      } catch ( Exception e ) {
         System.out.println( "No nimbus!" );
      }

      JSlider js = new JSlider();
      js.setPaintTicks( true );
      js.setPaintLabels( true );
      Border b = BorderFactory.createLineBorder( Color.black, 10 );
      js.setBorder( b );
      js.setOrientation( 1 );
      int imin = 0;
      int imax = 200;
      js.setMinimum( imin );
      js.setMaximum( imax );
      js.setMajorTickSpacing( ( imax - imin ) / 5 );

      setLayout( new FlowLayout() );
      add( js );
   }

   public static void main( String[] args ) {
      JFrame f = new JFrame( "Slider" );
      Slide mll = new Slide();
      f.getContentPane().add( mll );
      f.pack();
      f.setVisible( true );
   }
}
