Although the index of a changed element of an indexed property is known to
setter methods, there currently is no standard way to propagate this information
to listening clients, that is, classes IndexedPropertyChangeEvent and
IndexedPropertyChangeSupport are missing. A listener has to iterate over the
whole property to identify the element that has actually changed. This is
inconvenient in general, and unacceptable if the number of property elements is
large.

Feel free to use the implementation found in the workaround section. The method
signatures already take into account that non-int (ie, key) indexed properties
maybe are allowed in future Beans specifications. See Beans 1.01 spec (Section
7.2, "Indexed Properties", pages 40/41): "Property indexes must be Java
"int"s. We may relax this restriction in the future to allow other index types."
Size of compiled class files: 1792 bytes (IndexedPropertyChangeSupport) and
1100 bytes (IndexedPropertyChangeEvent).
