I'm using this code As found from "Item" Class however returning a false value inside the item class  returns a Null Point Exception.

I'm not Quite sure why could anyone tell me what I'm doing wrong please?

 
 

 @Override
public boolean isBookEnchantable(ItemStack stack, ItemStack book)
    {
        return false;
    }

Why are you using 1.11? If you must use 1.11.x, use 1.11.2. But you should really be using 1.12.1.

What you are experiencing here is a bug that was fixed in version 1.11.2-13.20.0.2210.

the issue is not corrected in 1.11.2-13.20.0.0.2210 it still exists as of  1.11.2 - 13.20.1.2386  Which leads me to assume its my fault although I'm not sure why. Also my Mod is not easily transferable to 1.12 as many things need to be done in regards to Recipe and Item registration which I'm not trying to deal with right now.

https://pastebin.com/vVMZifWy  I'm starting to think I need to null the parameters instead of returning false. because from the looks of it its the same error messages.

erm sorry it seems I messed up when setting up a new workspace x.x

Yes thank you for your time
