Uses the new ANSIComponentSerializer introduced in Adventure 4.14.0 to serialize components when logging them via the ComponentLogger, or when sending messages to the console. This replaces the old solution which uses legacy jank and custom color conversions, with a new library that handles the conversion and config

Subject: [PATCH] Synchronize PalettedContainer instead of
|
|
ThreadingDetector/Semaphore
|
|
|
|
Mojang has flaws in their logic about chunks being concurrently
|
|
wrote to. So we constantly see crashes around multiple threads writing.
|
|
|
|
Additionally, java has optimized synchronization so well that its
|
|
in many times faster than trying to manage read write locks for low
|
|
contention situations.
|
|
|
|
And this is extremely a low contention situation.
