This is for 2 reasons:
1) Ensuring our log4j is mostly loaded at OUR version.
I've seen stack traces with line numbers that do not match our version. This means that some
plugin has shaded in log4j and their loaded version is mixing with ours....
So by at least trying to load a bunch of log4j classes before we load plugins, we can be
more sure mixed versions are not loading.
2) If the jar file is replaced while the server is runnimg class not found errors galore
This will preloaod a bunch of classes commonly seen to error during shutdown due to this.
The goal here is to help let the server shutdown gracefully as possible. Some plugins will
still blow up here if they access a class that hadn't been loaded yet, but goal is to at least
stop freezing the shutdown process as it does with JLine and Log4j errors requiring an external kill.
Ideally you should not replace jars while the server is running, but it is something that happens in
development for testing.
Updated test server to do a copy though to avoid this happening in Paper development.
Blow up if a plugin tries to mutate visibleChunks directly and prevent them
from doing so.
Also provide a safe get call if any plugins directly call get on it so
that it uses the special logic to check pending.
Also restores ABI for the visibleChunks field back to what it was too.
Additionally, remove the stack trace from Timings Stack Corruption for any
error thrown on Minecraft Timings, and tell them to get the error ABOVE this
instead, so people stop giving us useless error reports.
Also fixes a memory leak when the source map down sizes but dest map didn't,
which resulted in lingering references to old chunk holders.
Fixes#3414
This adds the server property `Paper.DisableClassPrioritization` to disable
prioritization of own classes for plugins' classloaders.
This value is by default not present, and this will therefore break any
plugins which abuse behaviour related to not using their own classes
while still loading their own. This is often an issue with failing to
relocate or shade properly, such as when shading plugin APIs like Vault.
A plugin's classloader will first look in the same jar as it is loading
in for a requested class, then load it. It does not re-use other
plugins' classes if it has the chance to avoid doing so.
If a class is not found in the same jar as it is loading for and it does
find it elsewhere, it will still choose the class elsewhere. This is
intended behaviour, as it will only prioritise classes it has in its own
jar, no other plugins' classes will be prioritised in any other order
than the one they were registered in.
The patch in general terms just loads the class in the plugin's jar
before it starts looking elsewhere for it.
This also cleans up the implementation of Async Chunks to get rid of most
Consumer callbacks and instead return futures.
This lets us propogate errors correctly up the future chain
(barring one isn't lost even deeper in the chain...)
So exceptions can now bubble to plugins using getChunkAtAsync

If a server enables Anti Xray, packet sending can be delayed until the
chunk has been obfuscated, blocking the entire queue from going out.
On a busy server, considering Anti Xray can only operate on a single
thread, it is quite possible the obfuscation backlog can get quite behind
resulting in a delay of sending packets.
And logging in is a clear area where lots of chunks are going to be queued
for obfuscation....
We should probably special case a few more than this (such as chat),
but this will hopefully help the keep alive issues some people run into.

This is the start of a new module for Paper to add support for API's
that interface Mojang API's directly.
This allows us to version properly by MC version incase Mojang makes any major breaking changes.
It also lets us separate Mojang API's from Paper-API so our downstream friends at Glowstone
will not have to worry about Mojang code.
Adds AsyncPlayerSendCommandsEvent
- Allows modifying on a per command basis what command data they see.
Adds CommandRegisteredEvent
- Allows manipulating the CommandNode to add more children/metadata for the client
This event is called when processing a player's attack on an entity
right before their attack strength cd is reset, there are no existing
events that fire within this period of time so it was impossible to
capture the players attack strength via API prior to this commit.
The event is cancellable, which will just skip over the normal reset of
attack strength cd
Confused on this one, as commit history says Spigots version is older
than our version, so i'm not sure how we ended up duplicating this when
the 2 events are 100% identical.
Subclass spigots event and rely on the inheritance system, and clean up
the duplicate event fires.
Fix Spigots setPosition to use setPositionRaw to avoid chunk load prematurely.
Also check class loader cache before locking to speed up cached hits to avoid the lock
wasn't gonna make a unique build just for that but can lump it in here.
This is how it use to behave on Paper, and this is totally destroying
the ability to try to shut the server down gracefully during the
shutdown process as events firing on the watchdog thread are throwing
errors.
This isn't an issue on Spigot
This has caused me so many rollbacks on watchdog already :(
In most cases, this change won't benefit much. However, there
exists the possibility that your Chunk Task threads are all busy
doing super slow work such as converting chunks.
If this occurs, the main thread blocking tasks, even at highest priority,
has to wait for some thread to become available.
This change gives us a waiting thread used only for main thread blocking
tasks, as well as an increased thread priority level, so that the OS
will give priority to this thread over the other threads.
This is more about guarantees, and won't be any real performanc boost
to anyone who has low or fast activity on their chunk tasks anyways.
But not all of us force upgrade our worlds, and this can be a life saver.
also reordered some patches because multiple PR's were merged.
