PlayerLoginEvent fires twice
Expected behavior
When a player connects, the event should only fire once
Observed/Actual behavior
The event fires twice
Steps/models to reproduce
Add the below event listener to your plugin (This event listener can be replaced by turning on the whitelist and looking at the "Disconnecting" logs. The addition of code just makes it a bit easier to see)
@EventHandler
public void playerLoginEvent (PlayerLoginEvent event) {
System.out.println("Testing");
}
Join on an account and "Testing" will be logged twice

As far as I can tell, when the Connection is first disconnected, the channel is requested to close, but upstream removed the "await" part of that close, so the next tick happens and the channel isn't fully closed which makes the player's login be attempted to be handled again.
I can't seem to reproduce this, was this fixed already?

I can still reproduce this, was also able to get it to fire 3 times sometimes
