There is still plenty of new development going on in Java, and I hope that continues. But I'd be afraid that if Java is all you know, you're going to increasingly be stuck on critical legacy JEE / Spring apps at banks, insurance companies, etc. Right now that's okay - there's still a lot of innovation in these frameworks.
