JSplitPane component sometimes behaves incorrectly.

For example, please start JCK1.4a interactive test
api/javax_swing/interactive/JSplitPaneTests.html#JSplitPane[JSplitPaneTest0005] and do
the following:

1. Move tested JSplitPane divider down as far as possible.
2. Go to the JSplitPane bottom JTextArea component and click "Enter" several times there.
There are no visible changes in JSplitPane after the first clicking, top and bottom
textareas and divider pozition remain the same. But after 11 clicking divider moves up
unexpectedly, so textareas change their size.

The following test example demonstrates another situation like the one described here:

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

public class test extends JFrame implements ActionListener {
   JSplitPane sp;

   public test() {
      super("JSplitPane test");

      sp = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, true, new JTextArea(), new JTextArea());
      getContentPane().add(sp,BorderLayout.CENTER);
      sp.setDividerLocation(150);
      ((JTextArea)sp.getRightComponent()).insert("1234567890123456789012345678901234567890123456789012345678901234567890",0);

      JButton b = new JButton("Check!");
      b.addActionListener(this);
      getContentPane().add(b, BorderLayout.NORTH);
    }

   public static void main(String[] args) {
      JFrame frame = new test();
      frame.setSize(new Dimension(400,200));
      frame.setVisible(true);
    }

   public void actionPerformed(ActionEvent e) {
      System.out.println("SplitPane preferred size: " + sp.getPreferredSize());
      System.out.println("Min divider location: " + sp.getMinimumDividerLocation());
      System.out.println("Max divider location: " + sp.getMaximumDividerLocation());
      System.out.println("Divider location: " + sp.getDividerLocation());
      System.out.println("Right component min size: "+sp.getRightComponent().getMinimumSize());
      System.out.println("Right component size: "+sp.getRightComponent().getSize());
      System.out.println("----------------------------------");
     }
 }
---------------------------------------------------

Please, compile and run this test example.

Tested JSplitPane contains two JTextArea components. It is expected that divider can be moved
left because left textarea is empty and right textarea contains long string which exceed the
splitpane size. But actually you can not move divider.

Please, click "Check!" button to see tested splitpane and textareas parameters.
If you did not resize tested frame, test output is:

...
SplitPane preferred size: java.awt.Dimension[width=412,height=17]
Min divider location: 1
Max divider location: 1
Divider location: 140
Right component min size: java.awt.Dimension[width=400,height=15]
Right component size: java.awt.Dimension[width=239,height=146]
----------------------------------
...

Problem is that divider location can be more than max divider location or less then min divider
location (as in the test example). In this case it is inpossible to move the divider manually
even in it's correct location.
