This class implements accessibility support for the
JTextComponent
class. It provides an implementation of
the Java Accessibility API appropriate to menu user-interface elements.
Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. A future release of Swing will provide support for long term persistence.
