* that's shared by all JLabel objects.
* <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.
