Update to spigot-1.17.jar: No JavaScript Engine available (mac)

I have recently upgdated to Spigot 1.17. Now if I try to run any javascript commands from within the game nothing happens, and I get this message from the server (the following is produced if I try to do 1+1, but the same happens for any ScriptCraft functions):

[14:51:17] [Server thread/INFO]: nsm99999 issued server command: /js 1+1 
[14:51:17] [Server thread/ERROR]: [scriptcraft] No JavaScript Engine available. ScriptCraft will not work without Javascript.

I also had to update my version of java (on MacOS Big Sur) for the Spigot update, so that may be causing the problem. My version is:

$ java -version
openjdk version "16.0.1" 2021-04-20
OpenJDK Runtime Environment Homebrew (build 16.0.1+0)
OpenJDK 64-Bit Server VM Homebrew (build 16.0.1+0, mixed mode, sharing)

Any ideas? I realise that this may not be a ScriptCraft problem, but I guess others on macs might experience it with the new Java update.

Thanks in advance! (And thanks for ScriptCraft, it’s fantastic, my kids have just discovered the castle() method and are desperate to try it out)

Hey ScriptCrafters - I was able to get a working version with Java 16 using the Standalone Nashorn. It’s really messy (I don’t do any Java development and so don’t understand the toolchain).

The branch is here: https://github.com/davidyang/Scriptcraft

It still works with ant (I added Ivy and changed the .classpath since I was using Eclipse to get autocomplete).

Would love to merge this into main and have a working Scriptcraft - this really is the best plugin for building in Minecraft that I’ve found.

Hey! Sorry, that would be something @walterhiggins would have to implement.
