The Oracle JVM is now available on ARM. (I'm not sure if the ARM port is 
open sourced as part of OpenJDK or not.) At JavaOne this year, Oracle 
announced Java for Embedded; a significant amount of the customers and 
partners in this area are using ARM. Among other things, Java for Embedded 
supports the Java EE 6 standard, which includes lightweight web profile 
development support (using the Glassfish server -- see 
http://glassfish.org).

Nashorn is built on top of the JVM, and thus will run on any compliant JVM 
implementation on any platform. It should be pretty easy to run Node on ARM 
using Nashorn. And of course, V8 can also run on ARM.

There are still a number of micro-benchmarks in which Nashorn trails V8, 
but it is able to take advantage of the Hotspot dynamic native compilation 
(using runtime profiling to hyper-optimize hot spots within the code), 
which should make the overall performance significantly better. The JVM is 
also designed to take advantage of multi-core and multi-threaded 
architectures, which is an area that ARM is rapidly growing into.

Peace,
