I have created a custom basic item and it works fine as long as you don't try to craft the Item. As soon as you place teh last item in the crafting table Minecraft shuts down the internal server and closes. It says it can't get the Item Damage (The item should not be damageable)

This is in the console:

Thank you

Virhonestum

We can't do anything without your code.

 

Base class, the items you use to craft the item, etc.

Without code we can't help you, although this is particularly puzzling:

 

java.lang.NullPointerException: Rendering item
   at net.minecraft.item.ItemStack.getItemDamage(ItemStack.java:266)

 

NPE at getItemDamage() ?!

 

ItemStack.java:266
        return getItem().getDamage(this);

I'm guessing your ItemStack has somehow been initialised with a null Item.  I suspect the ItemStack you have specified as the output of the crafting recipe is not properly initialised.
