Thanks for reporting. Will need your help to fix this, as this issue is very much dependent on the code running on your particular devices. The recommended way to get to the bottom of this is to use a setup like this, allowing you to add temporary logging to a local copy of frida-java. That way you can figure out what's going on in recompileExceptionClearForArm64, or the similarly named function next to it in case the target process' architecture isn't arm64.

Hi. I have the same error on the latest frida (12.6.10)

An exemplary code that is causing errors:

function enumerateLoadedClasses() {
	var loadedClasses;

	if (Java.available) {
		Java.perform(function () {
			console.log("Enumerating loaded classes")
			loadedClasses = Java.enumerateLoadedClassesSync();
		});
	}
}

To anyone ending up here and: I started getting the same error (with TypeError: cannot write property '_code' of null) after updating Frida, and trying to use it on Android 6. It seems that simply Frida is tested on new Android versions, and old ones may become incompatible. Try downgrading Frida server, changing from version 12 to version 11 solved it for me.
