Updated Upstream (Bukkit/CraftBukkit)
Upstream has released updates that appears to apply and compile correctly.
This update has not been tested by PaperMC and as with ANY update, please do your own testing

My recent work on serialization is now in CraftBukkit so was able to drop the patch and Paper
is now consistent with upstream.

Bukkit Changes:
e2699636 Move API notes to more obvious location

CraftBukkit Changes:

Subject: [PATCH] Optimize CraftBlockData Creation
Avoids a hashmap lookup by cacheing a reference to the CraftBlockData
and cloning it when one is needed.
