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.
