CraftBukkit removed their implementation that caused this issue, switching to Mojang's implementation which doesn't appear to share it. I already removed the important bit in the last upstream merge, this is just unused and unnecessary now. So we remove it.

Subject: [PATCH] Use Optimized Collections
|
|
|
|
Swap out CraftBukkit LongObjectHashMap with Long2ObjectOpenHashMap
|
|
Swap out Integer key HashMap for a Int2ObjectOpenHashMap For ChunkProviderServer
|
|
|
|
Amaranth, the creator of LongObjectHashMap, tested it vs fastutil and determined fastutil to be 3x faster
|
|
and could not create anything faster than fastutil.
|
|
|
|
These collections are super fast as seen
