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
Refactored 0229-Fix-this-stupid-bullshit in order to prevent merge conflicts
when spigot decides to update the timer and to provide some form of hint in the
console/log on startup.
the first 'major' change in this PR is to cache the generated event
executrs from the ASM class, by doing this we only generate a single
class for every method that we need an executor for, thus reducing the
number of classes that are needed, especially in cases where plugins
re/unregister events all the time.
The second change is to modify the generated classloader map, generated
classloaders are not held against the plugin itself but the classloader
that the event is declared in, the implication here is that we cannot
drop generated classloaders when a plugin disable, and so we use a guava
weak-key'd hashmap, downfall here is that classes won't be GC'd until
guava drops the generated classloader, however the first change should
deal with most of the grunt.
Spigot has patched this issue inside MapIcon, meaning that we no longer need to maintain this patch; Spigots patch also fixes#668 in that it will verify the length of the array, as well as protect against a negative type value being fetched from the array. Only real change is that Spigots patch returns a MapIcon.Type.PLAYER, instead of the RED_MARKER as originally PR'd by Aikar.
Currently, when a player dies they are not automatically ejected from the entity they are riding, which allows
for the ridden entity to affect the players location on respawn (we're still riding it for a part of a tick), as well as allows a dupe to occur with the ridden entity teleporting to the new world with the player
