It's working out well as a 'forever' language: I can understand and use java code from the dawn of time (aka late 90s, but more realistically 1.5, 20 years ago), and Goetz seems to being doing well keeping that going. The challenge is adding any new features, but they are maintaining a reasonable cadence. At some point I imagine they will have to remove or at least isolate and disarm some ubiquitous core features (e.g. serialisation and synchronisation).
