Paper Console shutdown before all logs are written to it #13837
Description
Expected behavior
I would expect the console to print all the logs before shutting down.
Observed/Actual behavior
The console shutdown before all logs are printed to it.
Note: Do not confuse this with the .log file; The .log file is written to normally, it's just not printed in the terminal;
Steps/models to reproduce
- Start the server (I used the flags "@echo OFF
java -jar server.jar --nogui
PAUSE", I don't know if it's relevant to the cause of the issue)
-
Log in to the server
-
Type "stop" in the console
Okay, you will see that the logs in the terminal stop at:
[18:03:48 INFO]: [ChunkHolderManager] Waiting 60s for chunk I/O to halt for world 'minecraft:the_nether'
[18:03:48 INFO]: [ChunkHolderManager] Halted I/O scheduler for world 'minecraft:the_nether'
The following lines do not appear in the console (although they appear in the .log file):
[18:04:38] [Server thread/INFO]: [ChunkHolderManager] Saving all chunkholders for world 'minecraft:the_end'

This has been fixed by #14382, the server now waits for all lines to be flushed before the terminal output gets closed
