Java SE (Java Platform, Standard Edition)

I have a horizontal JSplitPane, the left side of which is occupied by a JTextArea and the right side by a JPanel, which will later contain a JList.

my problem is:
when resize I resize the window:
1. on expanding: the right side of the JSplitPane increases in size ( hence the JPanel increases in size ), while the JTextarea remains the same.
2. on contracting: the JTextArea keeps becoming smaller and until it nearly vanishes, and then the JPanel starts contracting.

It does not matter what corner or what size of the JFrame I use to resize it: the result is the same.

what do i do to reverse the effect but with the following difference:
On resizing, the following happens:
1. on expanding: the size of the JPanel remains the same, and the JTextArea keeps getting bigger
2. on contracting: the size of the JTextArea remains the same, and the JPanel contracts UNTIL IT REACHES A MINIMUM WIDTH. After this width, the JTextArea starts contracting, UNTIL THIS TOO REACHES A MINIMUM SIZE (both height and width). After this limit, no more contraction is possible.

My code is:

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

class MultiEditClient extends JFrame
{
	public MultiEditClient( String title )
	{
		super(title);
		
		addComponents();
		addMenu();
	}
	protected void addComponents()
	{
		this.setBounds( 100,100, 	500,500 );
		
		JPanel panel = new JPanel();
				
		JLabel label = new JLabel( "The to-be status bar." );
		label.setFont( new Font( Font.SANS_SERIF , Font.PLAIN , 14 ) );
		label.setMinimumSize( label.getMaximumSize() );
		
		JTextArea textarea = new JTextArea();
		textarea.setPreferredSize( new Dimension(400,400) );
		textarea.setMinimumSize( textarea.getMaximumSize() );
		JScrollPane scrollForTextArea = new JScrollPane(textarea);
		
		JPanel anotherpanel = new JPanel();
		anotherpanel.add( new JButton("Sample Button") );

		JSplitPane splitPane = new JSplitPane( JSplitPane.HORIZONTAL_SPLIT, scrollForTextArea, anotherpanel );
		splitPane.setOneTouchExpandable(true);
		
		panel.setLayout( new BoxLayout(panel, BoxLayout.PAGE_AXIS ) );

		Box vBox = Box.createVerticalBox();
		
		Box hBox2 = Box.createHorizontalBox();
		hBox2.add( splitPane );
		
		vBox.add( hBox2 );
		
		vBox.add( Box.createVerticalStrut(5) );
		
		Box hBox = Box.createHorizontalBox();
		hBox.add( Box.createHorizontalStrut(5) );
		hBox.add( label );
		hBox.add( Box.createHorizontalGlue() );
		
		vBox.add( hBox );
		
		vBox.add( Box.createVerticalStrut(2) );
		
		panel.add( vBox );
		add( panel );
	}
	protected void addMenu()
	{
		JMenuBar menubar = new JMenuBar();
		JMenu session = new JMenu( "Session" );
		
		JMenuItem joinSession = new JMenuItem( "Join Session" );
		
		session.add( joinSession );
		menubar.add( session );
		
		this.setJMenuBar( menubar );
	}
	public static void main( String args[] )
	{
		MultiEditClient theFrame = new MultiEditClient( "MultiEdit Client" );
		theFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		theFrame.pack();
		theFrame.setVisible( true );
	}
