Adding double-buffered JPanel into a Box causes drawing problem. Run the following code to reproduce:
('button in a panel' was drawed 2 times in different location)

import java.awt.*;
import com.sun.java.swing.*;

public class BoxTest
{
    public static void main(String[] args){
        JFrame frame = new JFrame();

        Box box = new Box(BoxLayout.Y_AXIS);
        box.add(new JLabel("I am a label"));
        box.add(new JButton("I am a button"));

        JPanel panel = new JPanel();
        panel.add(new JButton("button in a panel"));

        box.add(panel);
        frame.getContentPane().add(box);
        frame.pack();
        frame.setVisible(true);
    }

}
