choosing a Java 2D Frame work

I’ve been programming with the swing components native to java and have decided that not only are these tools poor in performance and not designed for game developing in the first place. I’ve done some searching around the forums and seen many people talk about Slick2D but I am skeptical about learning how to use a library that is no longer supported by its developers (not that I am saying its a bad library.) and I also cannot find it on the net anyway. So my question is what are some Rivals of Slick2D or something similar to take its place. My goal here is to make a 2D RPG if that helps narrow down what I’m lookin’ for thanks guys for any help you can give.
