how to help with ES6 features

[Paulo Lopes]

I can make it work with nashorn. Currently it does run on nashorn jdk8 plus
I need a executor impl for the async part. Of course I'm using vert.x for
this ;) However this could be a runtime configuration and by default use a
simple ThreadPool as it exists on the JDK itself and allow (say with some
runtime config) to provide a custom executor.

The executor is basically the equivalent of the not yet standard:

setImmediate(function);

Or node's:

nextTick(function);

So in nashorn it can be just a java.lang.Runnable and a ThreadPoolExecutor.

Cheers,
Paulo
