This patch intends to bump up the time that a client has to reply to the
server back to 30 seconds as per pre 1.12.2, which allowed clients
more than enough time to reply potentially allowing them to be less
tempermental due to lag spikes on the network thread, e.g. that caused
by plugins that are interacting with netty.
We also add a system property to allow people to tweak how long the server
will wait for a reply. There is a compromise here between lower and higher
values, lower values will mean that dead connections can be closed sooner,
whereas higher values will make this less sensitive to issues such as spikes
from networking or during connections flood of chunk packets on slower clients,
at the cost of dead connections being kept open for longer.
In 1.12.2, Mojang moved the processing of ServerboundKeepAlivePacket off the main
thread, while entirely correct for the server, this causes issues with
plugins which are expecting the PlayerQuitEvent on the main thread.
In order to counteract some bad behavior, we will post handling of the
disconnection to the main thread, but leave the actual processing of the packet
off the main thread.
also adding some additional logging in order to help work out what is causing
random disconnections for clients.
Disable the 15 second sleep when the server jar hasn't been rebuilt within a period of time.
modified in order to prevent merge conflicts when Spigot changes/disables the warning,
and to provide some level of hint without being disruptive.

They block. On network I/O.
If enough tasks are submitted the server will eventually stall
out due to a sync load, as the worldgen threads will be
stalling on profile lookups.
Makes parrots not fall off whenever the player changes height, or touches water, or gets hit by a passing leaf.
Instead, switches the behavior so that players have to sneak to make the birds leave.
I suspect Mojang may switch to this behavior before full release.
To be converted into a Paper-API event at some point in the future?

The watchdog thread calls the server restart function asynchronously. Prior to
this change, it attempted to do several non-safe operations from the watchdog
thread, rather than the main. Specifically, because of a separate upstream change,
it causes player entities to be ticked asynchronously, among other things.
This is dangerous.
This patch moves the old handling into a synchronous variant, for calls from the
restart command, and adds separate handling for async calls, such as those from
the watchdog thread.
When calling from the watchdog thread, we cannot assume the main thread is in a
tickable state; it may be completely deadlocked. In order to handle this, we mark
the server as stopping, in order to account for situations where the server should
complete a tick reasonbly soon, i.e. 99% of cases.
Should the server not enter a state where it is stopping within 10 seconds, We
will assume that the server has in fact deadlocked and will proceed to force
kill the server.
This modification does not force restart the server should we actually enter a
deadlocked state where the server is stopping, whereas this will in most cases
exit within a reasonable amount of time, to put a fixed limit on a process that
will have plugins and worlds saving to the disk has a high potential to result
in corruption/dataloss.
Limit a single entity to colliding a max of configurable times per tick.
This will alleviate issues where living entities are hoarded in 1x1 pens
This is not tied to the maxEntityCramming rule. Cramming will still apply
just as it does in Vanilla, but entity pushing logic will be capped.
You can set this to 0 to disable collisions.
Allow configuring for cartographers to return the same map location
Also allow turning off treasure maps all together as they can eat up Map ID's
which are limited in quantity.
Make it so a Treasure Map does not target a structure outside of the
World Border, where players are not even able to reach.
This also would help the case where a players close to the border, and one
that is outside happens to be closer, but unreachable, yet another reachable
one is in border that would of been missed.
This prevents Entities from trying to run outside of the World Border
TODO: This doesn't prevent the pathfinder from using blocks outside the world border as nodes. We can fix this
by adding code to all overrides in:
NodeEvaluator:
public abstract BlockPathTypes getBlockPathType(BlockGetter world, int x, int y, int z);
to return BLOCKED if it is outside the world border.

Provides an API to control the loot table for an object.
Also provides a feature that any Lootable Inventory (Chests in Structures)
can automatically replenish after a given time.
This feature is good for long term worlds so that newer players

RegionFileCache prior to this patch would close every single open region
file upon reaching a size of 256.
This patch modifies that behaviour so it closes the the least recently
used RegionFile.
The implementation uses a LinkedHashMap as an LRU cache (modified from HashMap).
The maximum size of the RegionFileCache is also made configurable.
Vanilla stores how long a chunk has been active on a server, and dynamically scales some
aspects of vanilla gameplay to this factor.
For people who want all chunks to be treated equally, you can chose a fixed value.
This allows to fine-tune vanilla gameplay.
First, Enchantment order would blow away seeing 2 items as the same,
however the Client forces enchantment list in a certain order, as well
as does the /enchant command. Anvils can insert it into forced order,
causing 2 same items to be considered different.
This change makes unhandled NBT Tags and Enchantments use a sorted tree map,
so they will always be in a consistent order.
Additionally, the old enchantment API was never updated when ItemMeta
was added, resulting in 2 different ways to modify an items enchantments.
For consistency, the old API methods now forward to use the
ItemMeta API equivalents, and should deprecate the old API's.
Entities collision is checking for scoreboards setting.
This is very heavy to do map lookups for every collision to check
this setting.
So avoid looking up scoreboards and short circuit to the "not on a team"
logic which is most likely to be true.
Properly split up the chat and command handling to reflect the server now
having separate packets for both, and the client always using the correct packet. Text
from a chat packet should never be parsed into a command, even if it starts with the `/`
character.
Add a missing async catcher and improve Spigot's async catcher error message.

The process of determining an entity's exposure from explosions can be
expensive when there are hundreds or more entities in range.
This patch adds a per-tick cache that is used for storing and retrieving
an entity's exposure during an explosion.
