Invalid biome ID failure, need to check where those biome ID comes from

It comes from here: when a player joins for the first time the spawnLocation for the player is null in this piece of code: io.gomint.server.network.PlayerConnection#sendWorldInitialization, so the world spawn is used. In my case the problem is that the world spawn is 150, 75, 150. When calling world.getBiome(position) in io.gomint.server.world.WorldAdapter#getBiome the block coordinates are converted to chunk ones, resulting in 9, 9 for chunk x and chunk z. Then after the chunk is created with the chunk coordinates and generate=true, when getting the biome with chunk.biome(150 & 15, 150 & 15) we end up with chunk.biome(6, 6). In that method the biome ID is generated by shifting 6 four times to the left and adding 6 to it, both x and z are 6. The result is 96 + 6 = 102. When calling getByte on this.biomes in ChunkAdapter the ID turns out to be 119. There's no biome with such ID in the Biomes enum.
