Shutdown process is now improved to also shutdown cleanly when +not using restart scripts either. + +If a server is deadlocked, a server owner can send SIGUP (or any other signal +the JVM understands to shut down as it currently does) and the watchdog +will no longer need to wait until the full timeout, allowing you to trigger +a close process and try to shut the server down gracefully, saving player and +world data. + +Previously there was no way to trigger this outside of waiting for a full watchdog +timeout, which may be set to a really long time... + +Additionally, fix everything to do with shutting the server down asynchronously. + +Previously, nearly everything about the process was fragile and unsafe. Main might +not have actually been frozen, and might still be manipulating state. + +Or, some reuest might ask main to do something in the shutdown but main is dead. + +Or worse, other things might start closing down items such as the Console or Thread Pool +before we are fully shutdown. + +This change tries to resolve all of these issues by moving everything into the stop +method and guaranteeing only one thread is stopping the server. + +We then issue Thread Death to the main thread of another thread initiates the stop process. +We have to ensure Thread Death propagates correctly though to stop main completely. + +This is to ensure that if main isn't truely stuck, it's not manipulating state we are trying to save. + +This also moves all plugins who register "delayed init" tasks to occur just before "Done" so they +are properly accounted for and wont trip watchdog on init. + +diff --git a/src/main/java/io/papermc/paper/util/LogManagerShutdownThread.java b/src/main/java/io/papermc/paper/util/LogManagerShutdownThread.java +new file mode 100644 +index 0000000000000000000000000000000000000000..183e141d0c13190c6905dc4510d891992afef878 +--- /dev/null ++++ b/src/main/java/io/papermc/paper/util/LogManagerShutdownThread.java +@@ -0,0 +1,26 @@ ++package io.papermc.paper.util;
