The bug

Server won't close with enabled GS4 listener on stop command.
What I expected to happen was...:
Server stops and exit after "stop" command on console
What actually happened was...:
Server hangs and won't exit after:

[19:41:33] [Server thread/INFO]: Saving chunks for level 'world'/minecraft:overworld
[19:41:33] [Server thread/INFO]: ThreadedAnvilChunkStorage (world): All chunks are saved
[19:41:33] [Server thread/INFO]: Saving chunks for level 'world'/minecraft:the_end
[19:41:33] [Server thread/INFO]: ThreadedAnvilChunkStorage (DIM1): All chunks are saved
[19:41:33] [Server thread/INFO]: Saving chunks for level 'world'/minecraft:the_nether
[19:41:33] [Server thread/INFO]: ThreadedAnvilChunkStorage (DIM-1): All chunks are saved

How to reproduce

1. Enable query port in server.properties.

   enable-query=true
   

2. Start server

   [19:46:58] [Server thread/INFO]: Done (8.822s)! For help, type "help"
   [19:46:58] [Server thread/INFO]: Starting GS4 status listener
   [19:46:59] [Query Listener #1/INFO]: Query running on 0.0.0.0:25565
   

3. Enter stop command

   [19:47:06] [Server thread/INFO]: Stopping the server
   [19:47:06] [Server thread/INFO]: Stopping server
   [19:47:06] [Server thread/INFO]: Saving players
   [19:47:06] [Server thread/INFO]: Saving worlds
   [19:47:06] [Server thread/INFO]: Saving chunks for level 'world'/minecraft:overworld
   [19:47:07] [Server thread/INFO]: ThreadedAnvilChunkStorage (world): All chunks are saved
   [19:47:07] [Server thread/INFO]: Saving chunks for level 'world'/minecraft:the_nether
   [19:47:07] [Server thread/INFO]: ThreadedAnvilChunkStorage (DIM-1): All chunks are saved
   [19:47:07] [Server thread/INFO]: Saving chunks for level 'world'/minecraft:the_end
   [19:47:07] [Server thread/INFO]: ThreadedAnvilChunkStorage (DIM1): All chunks are saved
   

   → Server hangs and won't exit (java proccess is still alive).
