40 * <p>
41 * This class creates a {@link Map} view for APPLICATION scoped properties that
42 * gets exposed to endpoint implementations during the invocation
43 * of web methods. The implementations access this map using
44 * WebServiceContext.getMessageContext().
45 *
46 * <p>
47 * Some of the {@link Map} methods requre this class to

49 * try to avoid that as much as possible.
