Well actually, the JVM is probably the most potent platform when it comes to async I/O, not only because the standard nio library and the high-level wrappers, like Netty and Mina, are very mature, but also because you can compose blocking and non-blocking pieces of functionality like you cannot do with Node / V8.

Checkout Akka, it's awesome: http://akka.io/

There are very few libraries.

Are you trying to say that there are very few libraries for something that runs on the JVM?
