net.minecraft.inventory.IInventory.getContents()[Lnet/minecraft/item/ItemStack;[m

How are you doing the /give command e.g. /give username cake 1 or /give username 264 1

/give username 264 1

people say its a bukkitforge issue, but that was back at version 255 its 301 i have installed

EDIT

and both get the same error
