I've been using jde-mode for years. Recently I upgraded to emacs 23 which required upgrading jdee, which required upgrading cedet. I'm now running the latest jdee with cedet-1.0pre6. Unfortunately, functions like jde-import-kill-extra-imports no longer work, claiming that there are no imports, even when I have a rather long list of them. I suspect the problem is deep in the parsing since (semantic-fetch-tags) returns nil, as does (semantic-active-p).
