I've just built a local libbluray in a clean chroot with the dependency
on libbluray-bdj removed from the -dev package, installed that version
in another clean chroot and successfully built xine-lib-1.2 without any
apparent shlib changes in the libxine2-misc-plugins package.

It might be better to explain this a bit more. Is libbluray-bdj a media
format library *and* a java player or just the player/menus support?

What kind of packages would need to *build-depend* on the new -dev
package?

Also add something which explicitly says that using the new -dev
package is for those packages which expect to use/need Java.

Those kinds of questions probably need to be answered in the package
descriptions of the new -dev and of libbluray-bdj itself.

bdj is a hint, but IMHO it should be clearer how the bdj library
should be used and that using it involves adding Java to your
development environment. In most cases, unless someone is extending the
Java player classes, that shouldn't be necessary.

That's fine. It's just what xine-lib-1.2 needs.
