Creating a key item that will unlock a Lockable Chest no longer seems to be possible if the key name has ChatColor codes in it. I think this is because the meta display name is now a chat component, but locks are simple strings.

I have a test plugin here: https://github.com/NathanWolf/Bukkit-Unit-Tests/releases/tag/lockable

This plugin sets a lock on a chest to the same string as an item's display name, with a red color prefix.

I used the /data command to compare the Lock tag on the block versus the NBT display name data on the item, it looks something like this:

{"extra":[{"bold":false,"italic":false,"underlined":false,"strikethrough":false,"obfuscated":false,"color":"red","text":"KEY"}],"text":""}

But the chest data just has this:

{x: 4715, y: 63, z: -4619, Items: [], id: "minecraft:chest", Lock: "§cKEY"}

If a string with no color codes is used, it works fine- I'm not sure why though since inspecting the item still yields a JSON representation such as

{"extra":[{"text":"KEY"}],"text":""}

but the lock tag is just "KEY".

Is there some logic already for comparing the JSON to the old-style string?

I'm hoping this means it might be possible to fix the colored case as well, I will add any info I find if I can dig further.
