JsplitPane splitter takes up too much space.

Run the following sample:
package test;

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

public class GUI extends JFrame {
    JPanel contentPane;
    BorderLayout borderLayout1 = new BorderLayout();
    JSplitPane jSplitPane1 = new JSplitPane();
    JTabbedPane jTabbedPane1 = new JTabbedPane();
    JTabbedPane jTabbedPane2 = new JTabbedPane();
    JScrollPane jScrollPane1 = new JScrollPane();
    JTable jTable1 = new JTable();
    JScrollPane jScrollPane2 = new JScrollPane();
    JTable jTable2 = new JTable();
    JTable jTable3 = new JTable();
    JScrollPane jScrollPane3 = new JScrollPane();
    JScrollPane jScrollPane4 = new JScrollPane();
    JTable jTable4 = new JTable();
    JTable jTable5 = new JTable();

    /**Construct the frame*/
    public GUI() {
        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("Frame Title");
        jSplitPane1.setOrientation(JSplitPane.VERTICAL_SPLIT);
        contentPane.add(jSplitPane1, BorderLayout.CENTER);
        jSplitPane1.add(jTabbedPane1, JSplitPane.LEFT);
        jTabbedPane1.add(jScrollPane3, "jScrollPane3");
        jScrollPane3.getViewport().add(jTable4, null);
        jTabbedPane1.add(jScrollPane4, "jScrollPane4");
        jScrollPane4.getViewport().add(jTable5, null);
        jSplitPane1.add(jTabbedPane2, JSplitPane.RIGHT);
        jTabbedPane2.add(jScrollPane1, "jScrollPane1");
        jTabbedPane2.add(jScrollPane2, "jScrollPane2");
        jScrollPane2.getViewport().add(jTable3, null);
        jScrollPane1.getViewport().add(jTable1, null);
    }
}

package test;

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

public class TestMain {
    boolean packFrame = false;

    /**Construct the application*/
    public TestMain() {
        GUI frame = new GUI();
        //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 TestMain();
    }
}
