Removing JFrame title bar WITHOUT removing window border

Question

I've been searching for a while now, and the only solutions I found were just using
frame.setUndecorated(true);But this also removes the window border, which removes the ability to resize the window.
I need the title bar removed while still retaining the ability to resize the window.
There has got to be some way to do this.

import javax.swing.*;
import java.awt.*;
class Testing
  public void buildGUI()
    JFrame.setDefaultLookAndFeelDecorated(true);
    JFrame f = new JFrame();
    f.getLayeredPane().remove(f.getLayeredPane().getComponent(1));
    f.setSize(400,300);
    f.setLocationRelativeTo(null);
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.setVisible(true);
  public static void main(String[] args)
    SwingUtilities.invokeLater(new Runnable(){
      public void run(){
        new Testing().buildGUI();
}
