[BD-J] Is there any Blu-Ray Authoring Suite with full Java ME Development for Linux?

As the question says, is there any software at the moment you can create awesome BD-J Menus in Linux and author them.

I only could find some boring ""BD Structure"-only creation scripts, that creates a BDMV folder structure. That is not what I want: Menus written in Java are missing. Menus that appear when you press PAUSE while playing the movie, blah blah blah. You probably know what I mean.

EDIT: Also animations and all that kind of stuff...

BD authoring is not really supported under Linux, since it still has no support for creating the necessary UDF 2.5 file-system.
