I was actually referring to all the docs that *aren't* JavaDocs, like the tutorials, the CSS reference, the getting started guides, interop guides etc.
As far as I know they haven't been updated since Java 8, however the API is backwards compatible so they are still useful learning materials. I am also not sure if they're open source licensed though. It would be a huge pity and a big drag on adoption if the community had to effectively produce an all new set of non-API docs _from scratch_.
