1.37 - * and new value of the changed property. If the new value is a primitive
1.38 - * type (such as int or boolean) it must be wrapped as the
1.39 - * corresponding java.lang.* Object type (such as Integer or Boolean).
1.40 - * <P>
1.41 - * Null values may be provided for the old and the new values if their
1.42 - * true values are not known.

1.44 - * An event source may send a null object as the name to indicate that an
1.45 - * arbitrary set of if its properties have changed. In this case the
1.46 - * old and new values should also be null.
