FULL PRODUCT VERSION :
java version "1.4.2_05"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_05-b04)
Java HotSpot(TM) Client VM (build 1.4.2_05-b04, mixed mode)

A DESCRIPTION OF THE PROBLEM :
The mouse listener removed twice in javax.swing.plaf.basic.BasicButtonUI#uninstallListeners.

The line 174 is unnecessary. Here is the source code of #uninstallListeners:

    protected void uninstallListeners(AbstractButton b) {
        BasicButtonListener listener = (BasicButtonListener) b.getClientProperty(this);
        b.putClientProperty(this, null);
        if(listener != null) {
            b.removeMouseListener(listener);
            b.removeMouseListener(listener); //!!! <-- This line is unnecessary !!!!
            b.removeMouseMotionListener(listener);
            b.removeFocusListener(listener);
            b.removeChangeListener(listener);
            b.removePropertyChangeListener(listener);
        }
    }

Please, don't forget to fix this in JDK 5.0 too!
