Anvils can insert it into forced order, +causing 2 same items to be considered different. + +This change makes unhandled NBT Tags and Enchantments use a sorted tree map, +so they will always be in a consistent order. + +Additionally, the old enchantment API was never updated when ItemMeta +was added, resulting in 2 different ways to modify an items enchantments. + +For consistency, the old API methods now forward to use the +ItemMeta API equivalents, and should deprecate the old API's. + +diff --git a/src/main/java/net/minecraft/world/item/enchantment/ItemEnchantments.java b/src/main/java/net/minecraft/world/item/enchantment/ItemEnchantments.java +index b49eb019cce58049c2b3a0e80e3d08998b16f7ea..af18de11dd55938b6091f5ab183bd3fe4e8df152 100644 +--- a/src/main/java/net/minecraft/world/item/enchantment/ItemEnchantments.java ++++ b/src/main/java/net/minecraft/world/item/enchantment/ItemEnchantments.java +@@ -27,15 +27,27 @@ import net.minecraft.tags.TagKey;
