Want to go so far and make it part of jbosstools ? ;)

lets see what the performance impacts are - jsdt isn't exactly fast 
either.

Yeah I like this  - much simpler than other typedef descriptions found 
in
things like vjet and others.

Not really - I just don't want it to fail in a default install...i.e. 
should bundle a node.js engine
by default so no external node js is required (can still allow users 
override that but make the default
experience be a "it just works")

It is worth trying but since nashorn only runs on Java 8 it is not 
something we can/should depend on
while Java 6 is still big, but luckily java 7 is getting better ;)

Having nashorn as an option when you are running with jdk 8 would be 
interesting to see if it
works better or worse than rhino/node.js.
