Issue Description:

I installed minecraft(1.12.2) with latest CraftTweaker, GregTech and Shadows of Greg that are available on twitch launcher. Other than that, i have no mods except for their dependencies.

What happens:

I'm trying to compile and run a script that would dump all available recipemaps and their recipes to crafttweaker.log. Instead of getting some output or a compile error if there is any, i seem to get an exception originating in the compiler itself. See pastebins of crafttweaker.log and my script file for details

What you expected to happen:

Either script output or some compile/run time error originating in my script.

Affected Versions (Do not use "latest"):

• Minecraft: 1.12.2
• Forge: forge-14.23.5.2847
• Crafttweaker: CraftTweaker2-1.12-4.1.19.jar
• Using a server: no
• If yes, does the client have the exact same scripts?

having experimented a bit, it seems to me that CraftTweaker has difficulties dealing with List<?> types, like List<IItemStack> that the getter aRecipe.outputs generates. I don't know if i can even specify the type template like List<> in ZenScript. The only method i found to convert List<?> to an array seems to be with a for-loop:

	var outputArray as IItemStack[] = [];
	for anItemStack in aRecipe.outputs {
		outputArray += anItemStack;
	}

as a simple list.toArray() or even list.toArray([] as IItemStack[]) don't work either.

Hm... it should not have any issue as long as the type is actually known and not a generic constraint like

public List<T> getXYZ()

IIngredient#getItems returns a List as well.

Also, to answer your question

[] as IItemStack[]; //Java Type: IItemStack[]
[] as [IItemStack]; //Java Type: List<IItemStack>

Ah, from another look it seems that this is already fixed in dev, there was a problem with List<-> Array casters at some point ^^

At least in my dev workspace the file you posted in the original report worked without problems
