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.

Subject: [PATCH] Don't move existing players to world spawn
|
|
|
|
This can cause a nasty server lag the spawn chunks are not kept loaded
|
|
or they aren't finished loading yet, or if the world spawn radius is
|
|
larger than the keep loaded range.
|
|
|
|
By skipping this, we avoid potential for a large spike on server start.
