Looking over the code, this appears to be one "high risk but hopefully unlikely that plugins are causing this to break", this line is however redundant leftovers from spigots tick limiter patch, which should be doing nothing as-is.

Subject: [PATCH] Optimize getChunkIfLoaded type calls
|
|
|
|
Uses optimized check to avoid major locks and large method.
|
|
|
|
Will improve inlining across many hot methods.
|
|
|
|
Improve getBrightness to not do double chunk map lookups.
