java.lang.Object | +--java.beans.PropertyChangeSupport | +--javax.swing.event.SwingPropertyChangeSupport
This subclass of java.beans.PropertyChangeSupport is identical in functionality -- it sacrifices thread-safety (not a Swing concern) for reduce memory consumption, which helps performance (both big Swing concerns). Most of the overridden methods are only necessary because all of PropertyChangeSupport's instance data is private, without accessor methods.
