font-lock-add-keywords turning off font-lock-mode

Hello,
I have a piece of lisp in my configuration:

(add-hook 'java-mode-hook
  (lambda ()
   (font-lock-add-keywords nil
    '(("\\<\\(FIXME\\):" 1 font-lock-warning-face prepend)))))

When this is run, font-lock mode is turned off whenever I open a java file.
Turning font-lock-mode back on works, sans the highlighting of FIXME.
Executing the body of the lambda in a buffer works fine.  Does anyone know
what the problem is?

Thanks,
Nathaniel Flath

Not really, but I've suffered from a similar problem using emacs 24 from
the bzr repo.  But since I updated my copy yesterday, it works again.
