MC-5413Items with NBT data do not stack correctly due to serialization
Items in inventory do not stack consistently depending on if they were created before or after when you last logged out or did a Save and Quit.
Steps to reproduce:
1. Name a block of dirt "A" using the anvil.
2. Name another block of dirt "A" and see that it does stack with the first.
3. Save and Quit then open the world again.
4. Name a third block of dirt "A" and see that it does NOT stack with the first two.
5. Save and Quit then open the world yet again.
6. See that now all three blocks of dirt stack together correctly.

When you give an item with the exact same NBT Data as you already have in your inventory, the items do not stack, only after logging out and back in.
How to reproduce:
-execute:
/give @p 1 1 0 {ench:[{id:1}]}
-log out and back in
-execute:
/give @p 1 1 0 {ench:[{id:1}]}
-the items do not stack
-log out and back in
-the items now stack
Notes:
-This problem existed before using renaming stuff in an anvil MC-5413
-You do not always have to log out and back in sometimes waiting a few seconds also works

Confirmed.

I can confirm this bug for 13w06a. It's really annoying for item sorters. I also noticed the NBT data is just the same.
Confirmed and voted.
for some reason, it does work after a while, I'm not sure when, but I sucked an item up in a hopper then dropped it again using a dropper, then they did stack.
Confirmed for 13w07a btw
confirmed for 13w09a
this bug sort of exists again in 13w36b using the /give command:
MC-30468It "reproduce" some times on multiplayer servers.
I am still experiencing this bug in 1.12 on play.wildcraftmc.com
It works fine for me. I assume it's only an issue because of modified server software (e.g. Bukkit/Spigot).
