Fix Version/s: None
This report only describes that an enchantment is shown which is not available. See
MC-30730, which describes the general behavior that an enchantment table may provide less than three enchantments.
When enchanting fishing rods, you are not able to apply low level enchants; the bug here is that these enchants still appear as if they could be selected. They should be greyed out.
See attached image: The first slot, which the mouse is hovering over, does not display any promised enchant in the tooltip and clicking it does nothing, yet it's not greyed out like the middle slot.
Here is an example in video: Unavailable enchants are not greyed out (fishing rod).mp4
The following is based on decompiled version of Minecraft 1.9 using MCP 9.24 beta. All method and class names are the names used in the decompiled version.
The reason why this happens is because the enchantment level returned by the method net.minecraft.enchantment.EnchantmentHelper.calcItemStackEnchantability(Random, int, int, ItemStack) is used. This method always returns at least 1 for the first enchantment (0 meaning no enchantment available). I am not sure if this can be fixed in this method, however what can be done is having the method net.minecraft.inventory.ContainerEnchantment.onCraftMatrixChanged(IInventory) set 0 as enchantment level if no enchantments are available.
This might not be the best solution and is only a suggestion.
