 /**
- * By default, when the DispatcherServlet can't find a handler for a request it
- * sends a 404 response. However, if its property "throwExceptionIfNoHandlerFound"
- * is set to {@code true} this exception is raised and may be handled with
- * a configured HandlerExceptionResolver.
- *
+ * Since 6.1: When the DispatcherServlet can't find a handler for a request, this 
+ * exception is raised and may be handled with a configured HandlerExceptionResolver. 
+ * However, if its (depricated) property "throwExceptionIfNoHandlerFound"
+ * is set to {@code false} it sends a 404 response.
+ * 
+ * <p><strong>Note:</strong> until 6.1 the default was to send a 404 response unless 
+ * throwExceptionIfNoHandlerFound was set to {@code true}
