Change Document Library Folder Name from client (JavaScript (JSOM) or Rest)

Hi

According to :

http://social.technet.microsoft.com/Forums/sharepoint/en-US/23441a0d-022a-4d97-8058-b75f32e342d2/rest-api-to-rename-the-folder-move-folder-copy-folder-prog-lang-is-java?forum=sharepointdevelopment

Renaming a folder with Rest is not possible.

and based on:

http://msdn.microsoft.com/en-us/library/office/jj245697(v=office.15).aspx

name property doesn't have any set.

Is it means that renaming a folder is not possible by JSOM or REST?!

Regards
