JNI attached native thread (null caller frame) cannot access a member of class java.util.ArrayList$Itr (in module java.base) with modifiers "public"

Text error (I used OCR so some things might be wrong):

Uncaught Exception:
Error: Error running instance method
java.lang.IllegalAccessException: JNI attached native thread (null caller frame) cannot access a member of class java.util.ArrayList$Itr (in module

Code (JS):

console.log(proxyPass.packetQueue.iteratorSync().nextSync())

Property (Java) that it's accessing:

public static ArrayList<JsonPacketData> packetQueue = new ArrayList<>();

Seems to be related to https://bugs.openjdk.java.net/browse/JDK-8221530, as it says null caller frame? But I think I'm using Java 14 so that should be fixed?

Seeing this same issue using Java 17. Is there a fix or a work around?
