Description

Whenever I stop the server with certain plugins installed, I get a WARN message: [Exit Thread/WARN] [Arclight/]: 20 threads not shutting down correctly, force exiting

I tested all my plugins individually, and figured out that these plugins cause the warning to appear:

AnimatedScoreboard.jar CoreProtect DiscordSRV FastAsyncWorldEdit (with patcher-loader-1.0.0) LuckPerms-Bukkit Multiverse-Core Multiverse-Inventories Multiverse-NetherPortals PlaceholderAPI Plan VotingPlugin

If any of these plugins are installed on their own (with no other plugins), the warning will show 1 thread not shutting down correctly. The exception is VotingPlugin which shows 11 threads not shutting down correctly

Step to reproduce

1. Install the latest dev build of Arclight (arclight-1.16.5-1.0.22-SNAPSHOT-7c63a9e)
2. Install any of the plugins from the list in the description
3. Start the server
4. Stop the server
5. Check the console or latest.log. The last line is XX threads not shutting down correctly, force exiting

MVCore does not show that for me, are you using the latest version? Also, if FastAsyncWorldEdit is a fork of the original WorldEdit, it may not support the hybrids(including Arclight).

Please demonstrate the version of plugins you've applied to server and I'll check the exact version with my latest build.

[IzzelAliz]

This is fixed in latest build.

[Flarkinater]

This is fixed in latest build.

Can you explain what you mean by this? As far as I know I'm using the latest dev build for 1.16.5 (1.0.22-SNAPSHOT-7c63a9e)

Maybe the force exiting thread. They "fixed" with using that method, on 1.16.5-1.0.22. But when to restart: the main thread doesn't stop but the new one opens, causes the log file to be failed writing.(Because of this I think it's not perfectly fixed though)
