Switch to a standard fixed size ThreadPoolExecutor as we don't use the advanced capabilities of a ForkJoinPool. ForkJoinPool does not allow single threads, and really rather not use 2 different executor types based on core count. Also, change thread priorities so that main thread is prioritized by the OS at a higher priority than the other threads. May not help too much but it at least signals the OS the information to know main is more important.

Subject: [PATCH] Fix CraftServer#isPrimaryThread and MinecraftServer
|
|
isMainThread
|
|
|
|
md_5 changed it so he could shut down the server asynchronously
|
|
from watchdog, although we have patches that prevent that type
|
|
of behavior for this exact reason.
|
|
|
|
md_5 also placed code in PlayerConnectionUtils that would have
|
|
solved https://bugs.mojang.com/browse/MC-142590, making the change
|
|
to MinecraftServer#isMainThread irrelevant.
|
|
By reverting his change to MinecraftServer#isMainThread packet
|
|
handling that should have been handled synchronously will be handled
|
|
synchronously when the server gets shut down.
