When ChunkAccess was converted to an abstract class some versions ago, the code to initialise nibble arrays should have been moved. However, the code was not moved and so now mods constructing their own implementations of ChunkAccess would not have the nibble arrays initialised. This is ported to Paper from Starlight to keep the code base in sync, not because it fixes anything known.

Subject: [PATCH] Optimise Chunk#getFluid
|
|
|
|
Removing the try catch and generally reducing ops should make it
|
|
faster on its own, however removing the try catch makes it
|
|
easier to inline due to code size
