Run the following test case. You will see two text panes inside the
frame. Remove some text from the lower pane(leave one line). Move mouse
from outside/inside this pane. Eventually the panes will be resize so
that lower pane becomes smaller. Add some text to lower pane, repeat
mouse moves - lower pane will become bigger.

I noticed that JTabbedPane is important for the test to fail. Without it
nothing bad happens.

The bug was reproduced on Linux using 1.5.0b15.

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

public class TestTextAreaResize {

    public static void main(String[] args) {
        JFrame f = new JFrame("Test frame");
        f.getContentPane().setLayout(new BoxLayout(f.getContentPane(),
BoxLayout.Y_AXIS));
        Container cont = f.getContentPane();

        Container dbReportPanel = new JPanel();
        dbReportPanel.setLayout(new BorderLayout());
        cont.add(dbReportPanel);

        JTabbedPane mainPane = new JTabbedPane();
        mainPane.add("DB Report", dbReportPanel);
        
        cont.add(mainPane, BorderLayout.CENTER);

        Container headerCont = new Container();
        headerCont.add(new JLabel("Header"));

        Container centerCont = new Container();
        centerCont.setLayout(new BoxLayout(centerCont,
BoxLayout.Y_AXIS));
        dbReportPanel.add(centerCont, BorderLayout.CENTER);
        dbReportPanel.add(headerCont, BorderLayout.SOUTH);

        Container cont1 = new Container();
        cont1.setLayout(new BorderLayout());
        centerCont.add(cont1);
        cont1.add(new JLabel("Label1"), BorderLayout.NORTH);
        cont1.add(new JScrollPane(new JTextArea("Container cont1 = new
Container();\n" +
                                                "cont1.setLayout(new
BorderLayout());\n" +
                                               
"centerCont.add(cont1);")));

        Container cont2 = new Container();
        cont2.setLayout(new BorderLayout());
        centerCont.add(cont2);
        cont2.add(new JLabel("Label2"), BorderLayout.NORTH);
        cont2.add(new JScrollPane(new JTextArea("Container cont1 = new
Container();\n" +
                                                "cont1.setLayout(new
BorderLayout());\n" +
                                               
"centerCont.add(cont1);")));
        
        f.pack();
        f.setVisible(true);

    }
}
