We've applied a few band-aid solutions ahead of a larger refactor of the developer portal and documentation that is planned over the long term. Part of this is complicated by the fact that Java and other mid-level language APIs are deprecated and no longer formally supported, which invalidates a lot of the older docs; you'll notice they have developer-archive
as their subdomain for this reason. At the same time, though, we're actively looking into whether restoring support for languages like Java should be re-prioritized.
