Am I doing this wrong?

        Material[][][] template = new Material[][][] {
                {
                    { Material.GLOWSTONE, Material.BRICK, Material.BRICK, Material.BRICK, Material.GLOWSTONE },
                    { Material.BRICK, Material.BRICK, Material.BRICK, Material.BRICK, Material.BRICK },
                    { Material.BRICK, Material.BRICK, Material.BRICK, Material.BRICK, Material.BRICK },
                    { Material.BRICK, Material.BRICK, Material.BRICK, Material.BRICK, Material.BRICK },
                    { Material.GLOWSTONE, Material.BRICK, Material.BRICK, Material.BRICK, Material.GLOWSTONE },
                },
