I tried overriding getMinimumSize, as you suggested, but it had no 
effect.  In fact it never gets called :(

Did I do something wrong?

Here is a small two file test program.

====================================================================
TestApplication.java
====================================================================
package Test;

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

public class TestApplication {
  boolean packFrame = false;

  //Construct the application
  public TestApplication() {
    TestFrame frame = new TestFrame();
    //Validate frames that have preset sizes
    //Pack frames that have useful preferred size info, 
    //  e.g. from their layout
    if (packFrame) {
      frame.pack();
    }
    else {
      frame.validate();
    }
    //Center the window
    Dimension screenSize = 
      Toolkit.getDefaultToolkit().getScreenSize();
    Dimension frameSize = frame.getSize();
    if (frameSize.height > screenSize.height) {
      frameSize.height = screenSize.height;
    }
    if (frameSize.width > screenSize.width) {
      frameSize.width = screenSize.width;
    }
    frame.setLocation
      ((screenSize.width-frameSize.width)/2, 
       (screenSize.height-frameSize.height)/2);
    frame.setVisible(true);
  }

  //Main method
  public static void main(String[] args) {
    try {
      UIManager.setLookAndFeel
        (UIManager.getSystemLookAndFeelClassName());
    }
    catch(Exception e) {
      e.printStackTrace();
    }
    new TestApplication();
  }
}


====================================================================
TestFrame.java
====================================================================
package Test;

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

public class TestFrame extends JFrame {
  JPanel contentPane;
  BorderLayout borderLayout1 = new BorderLayout();

  //Override getMinimumSize
  public Dimension getMinimumSize(){
    return new Dimension(800, 600);
  }

  //Construct the frame
  public TestFrame() {
    enableEvents(AWTEvent.WINDOW_EVENT_MASK);
    try {
      jbInit();
    }
    catch(Exception e) {
      e.printStackTrace();
    }
  }

  //Component initialization
  private void jbInit() throws Exception  {
    contentPane = (JPanel) this.getContentPane();
    contentPane.setLayout(borderLayout1);
    this.setSize(new Dimension(400, 300));
    this.setTitle("Test Program");
  }

  //Overridden so we can exit when window is closed
  protected void processWindowEvent(WindowEvent e) {
    super.processWindowEvent(e);
    if (e.getID() == WindowEvent.WINDOW_CLOSING) {
      System.exit(0);
    }
  }
}
