Solved Impossible to populate a LootTable (Bukkit bug?)

I just wanted to generate a random item from the fishing loot table. Here is my code:

Code:

Random random = new Random();
LootTable fishingLoot = LootTables.FISHING.getLootTable();
LootContext.Builder builder = new LootContext.Builder(event.getPlayer().getLocation());
LootContext context = builder.killer(event.getPlayer()).build();
List<ItemStack> fishingDrops = (List<ItemStack>) fishingLoot.populateLoot(random, context);

for (ItemStack item:fishingDrops)
    Main.instance.console.sendMessage(item + "");

However the line

Code:

List<ItemStack> fishingDrops = (List<ItemStack>) fishingLoot.populateLoot(random, context);

Throws this error:

Code:

java.lang.IllegalArgumentException: Missing required parameters: [<parameter minecraft:tool>

From looking into the constructor there is no way to pass in this information (in this case the fishing rod used), it seems impossible. Is this a flaw of the Bukkit implementation or am I just stupid? Please help!

Edit: I solved it by copying the entire LootTable into my code! Love my life!
