* This change information may be sent out by an observable object when it wants

* the circular reference inherent to the observer pattern which makes it
* inaccessible for the garbage collector.

* <p>
* Its item is of type <code>java.util.Observable</code> and denotes the
* observable that should no longer be referenced.
