Enhance the throwAuthorizationFailure() method within the org.apache.cxf.rs.security.oauth2.utils.AuthorizationUtils class to add a descriptive message to the corresponding 401 response's message payload. The message should provide the reason for the 401 response code. For example, "expired token".
