I did some investigations on your problem.  With your above setup font
locking did not work with my NT Emacs 20.7.3 :-(  But it works well
with NT Emacs 21.0.

I think this is an Emacs 20.7 bug related to overlays (setup by
semantic in jde-mode but not in java-mode).  I got a similar problem
on my Solaris box with Emacs 20.7 and maintainers sent me a patch that
fixed it.

Try to do the following in your java buffer in jde-mode:

 M-: (mapcar 'delete-overlay (overlays-in (point-min) (point-max)))

And font locking should work.

Attached is the patch I received from Emacs maintainers.

I cced this message to Andrew Innes <[EMAIL PROTECTED]>.  May be could
he help.  Maybe could you send a bug report too.

Sincerely,
David

I think this should fix it for 20.7 (not a problem in the new face
implemenation).  Thanks, David.
