Changes in Java 9

I just switched to the Java 9.0.1 runtime, and Nashorn now fails to parse
the Coffeescript compiler, which worked fine in Java 8_144.

Coffeescript 2 compiler:
http://coffeescript.org/v2/browser-compiler/coffeescript.js

v1 also fails: http://coffeescript.org/v1/browser-compiler/coffee-script.js

Exception is:

Further testing with the un-minified code (cs2
<https://unpkg.com/***@2.0.3/lib/coffeescript/browser.js>, cs1
<https://unpkg.com/***@1.12.7/lib/coffee-script/browser.js>)
reveals the true problems in JDK 9.0.1

In cs2, it’s ES6 syntax (default args), which (unexpectedly for me at
least), works in JDK 8:

<eval>:46:45 Expected , but found =
CoffeeScript.eval = function(code, options = {}) {
^ in <eval> at line
number 46 at column number 45

And in cs1 it’s require that’s unresolved (also works in JDK 8):

ReferenceError: "require" is not defined in <eval> at line number 7

Ok, the minified vs non-minified may not be identical. I cannot find the
default parameters in the minified version, so perhaps those are removed.

What does remain however, is that I can compile minified cs2
<http://coffeescript.org/v2/browser-compiler/coffeescript.js> on JDK 8_144,
but not on 9.0.1.

Hi Nils,

Are you just evaluating the script files you linked in your first message, or trying to do some further processing?

Using the jjs tool from JDK 9.0.1 I see no errors running both versions of CoffeeScript.

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.
