Entity AI tasks are initialized earlier in recent versions
of MC, this means that the fromMobSpawner has not been set
at the point where AI tasks are initilazed and so the goalFloat
will never be populated.
To rectify this, we can rely on the entity tick checking if
the mob is from a spawner each tick, and just initialize the
field should the paper option be enabled. This saves us from
having to modify the call chain in order to pass the fact that
it was created by a mobSpawner earlier.
HashSet sometimes uses compareTo() instead of equals() and this breaks the comparison of net.minecraft.server.NextTickListEntry (the only place where HashTreeSet is used).
In this cases duplicate entries could be added to the HashSet of HashTreeSet, because NextTickListEntry.compareTo() does not return 0, even if NextTickListEntry.equals() returns true.
ObjectOpenHashSet never uses compareTo(), so the inconsistencies of NextTickListEntry cause no problems.

Will display a list of all entities in a world, as well as which chunks
they are in. Hopefully, this will make tracking down chunks with lots of
entities easier.
Only real change from the forge version is that instead of dimension
IDs, we accept world names in the form of a string.
/paper entity list - Lists all entities in the player's current world
/paper entity list minecraft:zombie - Lists all zombies in the player's
current world
/paper entity list * world_nether - Lists all entities in the nether
/paper entity list minecraft:ghast world_nether - Lists all ghasts in
the nether
This commit removes two patches from spigot:
please review the patch messages for more information, however;
"Allow Disabling of Random Lighting Updates" potentially leaves chunk light maps in an invalid state, with
how often the server looks at these anyways, this patch really serves a questionable nature, the work is
going to be done, only it's being delayed and allowing the light map to be left in a potentially outdated
state.
"Fix some chunks not being sent to the client" sends chunks before their lighting has been calculated, this
means that the client will recieve chunks before they lighting has been calculated which can cause rendering
artifacts. The original issue around this patch appears to have already been fixed years ago.
In 1.12.2, Mojang moved the processing of PacketPlayInKeepAlive 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
on the main thread.

Java decided to change their versioning scheme and in doing so modified the
java.version system property to return $major[.$minor][.$secuity][-ea], as
opposed to 1.$major.0_$identifier we can handle pre-9 by checking if the "major"
is equal to "1", otherwise, 9+
of course, it really wouldn't be all that simple if they didn't add a quirk, now would it.
valid strings for the major may potentially include values such as -ea to deannotate a pre release
Some plugins bypass the plugin logger and add the plugin prefix
manually to the log message. Since they use other logger names
(e.g. qualified class names) these would now also appear in the
log. Disable the logger prefix for these plugins so the messages
show up correctly.
Essentials uses a custom logger name ("Essentials") instead of the
plugin logger. Log messages are redirected to the plugin logger by
setting the parent of the "Essentials" logger to the plugin logger.
With our changes, the plugin logger is now also called "Essentials",
resulting in an infinite loop. Make sure plugins can't change the
parent of the plugin logger to avoid this.
SLF4J is a commonly used abstraction for various logging frameworks
such as java.util.logging (JUL) or Log4j. Currently, plugins are
required to do all their logging using the provided JUL logger.
This is annoying for plugins that target multiple platforms or when
using libraries that log messages using SLF4J.
Expose SLF4J as optional logging API for plugins, so they can use
it without having to shade it in the plugin and going through
several layers of logging abstraction.
Log4j2 provides an optimized implementation of PrintStream that
redirects its output to a logger. Use it instead of a custom
implementation for minor performance improvements and some fixes.
With the old implementation, each call to System.print()
results in a separate line, even though it should not result in
a line break. Log4j's implementation handles it correctly.
