Thanks for that comment. I have sent a pointer to it to the writer for that book. Note that with the New Features Guide, most of the content is automatically drawn from an internal system that tracks projects and features; so if a change is needed, the writer will notify the owner of that content (typically a developer or a product manager) to investigate and (if necessary) modify the underlying data, after which the changed information will be picked up for a future revision of the book.
Also, while anyone is welcome to enter documentation comments in this forum, another option that may be more convenient for comments on specific sections is the Reader Comment area at the bottom of each HTML page (such as http://docs.oracle.com/cd/E16655_01/server.121/e17906/chapter1.htm#NEWFT495 for the page containing Section 18.104.22.168). Any comments entered in a Reader Comment area go to someone in our documentation production group, who forwards them to the appropriate writers.
However, if a comment involves multiple HTML pages or books, or if you want the matter to be in a public forum for visibility and searchability, posting in this forum is a good option.

I use the PDF versions of the manuals and that's where I have found (and reported) several documentation errors. Going into the HTML versions of the manuals so that I can relocate the errors so that I can report them is not particularly convenient. I am perfectly happy to not bother reporting them, though, if you would prefer that. That would save me some time.
