Problem description
===================
Specification of the javax.swing.plaf.basic.BasicButtonUI.installUI()
method is not clear. It does not specify what will happen if
we install UI more than once, e.g. if we try to install UI over
another previously installed UI we'll get internal API errors.
Documentation does not describe this kind of method's behavior,
though, installing UI several times on the same components should
be explicitly specified. To see how it works, run the example below.

    
Minimized test:
===============
------- StubBasicButtonUI.java -------
import javax.swing.*;
import javax.swing.plaf.basic.*;
import javax.swing.event.*;
import java.util.*;
import java.beans.*;

public class StubBasicButtonUI extends BasicButtonUI {
  static JButton button = null;

  public StubBasicButtonUI() {
    super();
  }
  
  public BasicButtonListener createButtonListener(AbstractButton b) {
    return new BasicButtonListener(b) {
public void propertyChange(PropertyChangeEvent e) {}
      };
  }

  public static void main(String[] argv) {
    button = new JButton("Test");
    StubBasicButtonUI ui = new StubBasicButtonUI();
    System.out.println("BEFORE installUI()");
    printListeners();
    ui.installUI(button);
    System.out.println("AFTER installUI()");
    printListeners();
    ui.uninstallUI(button);
    System.out.println("AFTER uninstallUI()");
    printListeners();

  }

  static void printListeners() {
    EventListener[] list = button.getListeners(ChangeListener.class);
    int count = list.length;
    System.out.println("Button contains "+count+" ChangeListeners");
    for (int i=0; i<count; i++) {
      System.out.println(" "+list[i].toString());
    }
  }
}
