JTabbedPane layout problem

Question

I have a JTabbedPane as shown below:
|                          |
| ----- -----                         |
|  |   | |   |                        |
| ----------------------------------- |
| | --------------- --------------- | |
| | --------------- --------------- | |
| | --------------- --------------- | |
| | --------------- --------------- | |
| | --------------- --------------- | |
| | --------------- --------------- | |
| |_________________________________| |
|                                     |
--------------------------------------|As you can see, each tab has two columns and with 5 rows each column. Each row is a horizontal javax.swing.Box of components.
My problem sometimes I only have, for example, 2 rows in the second column. They become stretched to fill the remaining space and I don't like that.
How do I resolve this so it doesn't do that?
Thnks for any help!

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.Random;
public class Test extends JFrame {
  public Test() {
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    Container content = getContentPane();
    JTabbedPane jtp = new JTabbedPane();
    content.add(jtp, BorderLayout.CENTER);
    Random r = new Random();
    for (int i=0; i<2; i++) {
      JPanel tab = new JPanel(new GridLayout(6,2));
      jtp.add("Tab "+i, tab);
      for (int j=0; j<6; j++) {
        tab.add(new JLabel("Label-"+i+","+j+":", JLabel.RIGHT));
        if (j==0 || r.nextBoolean()) tab.add(new JTextField("Text-"+i+","+j));
        else tab.add(Box.createHorizontalBox());
    setSize(300, 300);
    setVisible(true);
  public static void main(String args[]) { new Test(); }
class MyCardLayout extends CardLayout {
  public void show();
}
