[1.9.4] BlockFurnace setState

[COM8]

I'm not really understanding why in the class "BlockFurnace", in the method "public static void setState(boolean active, World worldIn, BlockPos pos)"

the method "worldIn.setBlockState(...)" is called twice.

 

if (active)
        {
            worldIn.setBlockState(pos, Blocks.LIT_FURNACE.getDefaultState().withProperty(FACING, iblockstate.getValue(FACING)), 3);
            worldIn.setBlockState(pos, Blocks.LIT_FURNACE.getDefaultState().withProperty(FACING, iblockstate.getValue(FACING)), 3);
        }

 

Whole method:

public static void setState(boolean active, World worldIn, BlockPos pos)
    {
        IBlockState iblockstate = worldIn.getBlockState(pos);
        TileEntity tileentity = worldIn.getTileEntity(pos);
        keepInventory = true;

        if (active)
        {
            worldIn.setBlockState(pos, Blocks.LIT_FURNACE.getDefaultState().withProperty(FACING, iblockstate.getValue(FACING)), 3);
            worldIn.setBlockState(pos, Blocks.LIT_FURNACE.getDefaultState().withProperty(FACING, iblockstate.getValue(FACING)), 3);
        }
        else
        {
            worldIn.setBlockState(pos, Blocks.FURNACE.getDefaultState().withProperty(FACING, iblockstate.getValue(FACING)), 3);
            worldIn.setBlockState(pos, Blocks.FURNACE.getDefaultState().withProperty(FACING, iblockstate.getValue(FACING)), 3);
        }

        keepInventory = false;

        if (tileentity != null)
        {
            tileentity.validate();
            worldIn.setTileEntity(pos, tileentity);
        }
    }

 

Any help / information is appreciated.

Probably because Mojang did a dumb.

I've found duplicated lines in my code on occasion (setting a field to some value, then setting some other fields, then setting the first field again).

Ah, OK thanks
