You can't go wrong with either choice. Both languages are mature enough to be used in production. I, personally, would use Java, but that's just my preference.

Actually you don't really need any new features to write useful programs. They might help, but they are not necessary. My advice would be to learn both languages and use your own judgement which one you would like more.
