How disable semantic for specific mode?

I use only built-in GNU Emacs CEDET.

This articles provide solution:

http://thread.gmane.org/gmane.emacs.semantic/2439/focus=2440
http://thread.gmane.org/gmane.emacs.semantic/589/focus=592

but for me this instructions seems outdated or irrelevant for GNU Emacs 
built-in CEDET as none of *-mode-hook contain
'semantic-default-*-setup' (but I do not comment and recompile
semantic files).

I enable semantic by

   (semantic-mode 1)

Search for 'disable' in (info "semantic") take no result.

I want to disable Semantic for js-mode because of bug:

   http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8894
   'which-func-mode' can not find function when 'semantic' enabled.

   http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8445
   "wisent-parse-stream: #<buffer my.js> - Invalid start symbol 
bovine-inner-scope" in JavaScript with 
"(global-semantic-idle-summary-mode 1)"

Also I think semantic for JS less useful as JS not strong typed lang
and dabbrev completion work much fine.
