I first tried using ScriptCraft (3.4.0 jar) with Paper (“no javascript engine available”). Then I tried spigot but go the same error. I’m using java 17 and a recent build of MC. I tried jwulf’s patch to call ScriptEngineManager with a null arg.

I’m trying to build my own scriptcraft.jar. I’m currently stuck on ant gen-events-helper-bukkit which logs Cannot invoke "javax.script.ScriptEngine.put(String, Object)" because "<local2>" is null
