Compiled for Java 8 but crashing on it

[thecatcore]

Since 1.0.2, the mod is targeting Java 8, it runs well on Java 17, but crash on Java 8.
In my case, I'm using Fabric Loader 0.14.21.

ScriptEngineManager providers.next(): javax.script.ScriptEngineFactory: Provider jdk.nashorn.api.scripting.NashornScriptEngineFactory not found
