- * (currently this class is rigged to work with subclasses
- * of AbstractButton and JToolBar).
- * <p>
- * 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 Swing1.0 applications. It will
- * not be possible to load serialized Swing1.0 objects with future releases
- * of Swing. The JDK1.2 release of Swing will be the compatibility
- * baseline for the serialized form of Swing objects.
