How to control TitledBorder insets / margin / buffer / space?

Question

I'm trying to remove some space on my GUI. Here's a simple example, with a couple buttons in a JPanel with a TitledBorder.
Is there any way to decrease the space between the buttons and the border (especially the top one)?
I'm pretty sure it has something to do with the TitledBorder's insets, but I don't see any obvious way to decrease it.
I don't understand what the getBorderInsets() method does, or what I should pass to it.
Thanks!
import java.awt.BorderLayout;
import javax.swing.BorderFactory;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class Test
   public static void main (final String[] args)
      JPanel panel = new JPanel();
      panel.setBorder (BorderFactory.createTitledBorder ("Title"));
      panel.add (new JButton ("Button 1"));
      panel.add (new JButton ("Button 2"));
      JFrame frame = new JFrame();
      frame.add (panel, BorderLayout.CENTER);
      frame.pack();
      frame.setVisible (true);
}

I don't understand what the getBorderInsets() method does, or what I should pass to it.It returns the insets of the specified component.
So you need to override this method to return your required insets:
//TitledBorder border = BorderFactory.createTitledBorder ("Title");
TitledBorder border = new TitledBorder("Title")
     private Insets customInsets = new Insets(15, 5, 5, 5);
     public Insets getBorderInsets(Component c)
          return customInsets;
};
