How can I create JEditorPane which scrolls to the bottom on every resize?

Question

JRE 1.3.0
Included a simple frame with the only control - JEditorPane (contained within JScrollPane). Every time scroll pane size changes, attempt to scroll down to the end of JEditorPane is made.
The problem is: although everything works 9 times of 10, sometimes editor is scrolled almost to the end, sometimes - to the very top. On the next resize editor is scrolled correctly.
I think, there are some delayed layout recalculations inside SWING which prevent JEditorPane and/or JScrollPane from knowing actual size.
Is it possible to force JEditorPane+JScrollPane pair to update dimensions? ( explicit call to doLayout() does not fix anything )
Thanks
public class TestFrame extends JFrame
BorderLayout borderLayout1 = new BorderLayout();
JScrollPane jScrollPane1 = new JScrollPane();
JEditorPane jEditorPane1 = new JEditorPane();
public TestFrame()
try
jbInit();
catch(Exception e)
e.printStackTrace();
private void jbInit() throws Exception
this.getContentPane().setLayout(borderLayout1);
jEditorPane1.setContentType("text/html");
jEditorPane1.setText("test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test ");
jScrollPane1.addComponentListener(new java.awt.event.ComponentAdapter()
public void componentResized(ComponentEvent e)
jScrollPane1_componentResized(e);
this.getContentPane().add(jScrollPane1, BorderLayout.CENTER);
jScrollPane1.getViewport().add(jEditorPane1, null);
void jScrollPane1_componentResized(ComponentEvent e)
Dimension size = jEditorPane1.getPreferredSize();
jEditorPane1.scrollRectToVisible( new Rectangle(0, size.height, 0, 0) );
System.out.println("preferred height=" + size.height);
}
