Changes in Java 9

Mon Dec 4 15:56:45 UTC 2017

Thanks for bringing this up. It made me realize that my post was incomplete.

These are the steps I take:

   1. Initial step: Call engine.compile with the CS compiler source +
CoffeeScript.compile(coffeeCode,
   {runtime: 'none'}); which returns CompiledScript that is retained and
   re-used. This works fine, also on JDK 9.0.1.
   2. For subsequent Coffeescript -> Javascript transpilation, I then call
   engine.createBindings()
   3. Then bindings.put("coffeeCode", csCode) to associate the CS code with
   the JS variable coffeeCode mentioned in initial step
   4. Call CompiledScript.eval(bindings). This is the step that fails in
   9.0.1.

I’m open to better ways to achieve this, if it’s inefficient or plain wrong.
