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:
