Actually, time to look beyond the whole Java ecosystem. After the claims Oracle made during the Google trial (such as APIs and method signatures being patent-able), it is clear that one can't work on the Java platform without infringing Oracle's IP. If Oracle doesn't sue you now, it can sue you when it makes financial sense to do so. .Net looks like a much better alternative, with a patent pledge and ECMA standardiza…
I agree Java is dying, but so is .Net. Microsoft is trying it's best, but .Net Core is no where near as popular as .Net 3.5. (google trends). Embrace the Beam. :)
My world is pretty much divided between Java and .NET, with a sprinkle of C++.
