I have seen several similar things that essentially use existing Java libraries or the libraries themselves offer it (Javascript).
* jooby [1]
* Vert.x [2]
* Rapidoid (I can't find the exact link where JS was used) [3]
I'm just not entirely sure why you would trade a language that is generally much safer for one that is known to be problematic at scale particularly since Java 8 has lambdas so you can do callback async style if you like. I mean I suppose you could use typescript but at that point why not stick with Node and if you need JVM stuff just make some sort of microservice to access it from Node.
If it is a learning thing than (as Java is complicated) than Clojure is far better option (I'm always amazed how easy it is to learn any Lisp as syntax becomes a non issue).
