* and new value of the changed property. If the new value is a primitive
* type (such as int or boolean) it must be wrapped as the
* corresponding java.lang.* Object type (such as Integer or Boolean).
* <P>
* Null values may be provided for the old and the new values if their
* true values are not known.
* <P>
* An event source may send a null object as the name to indicate that an
* arbitrary set of if its properties have changed. In this case the
* old and new values should also be null.
