in `log': undefined method `add' for nil:NilClass

is this code deprecated in the current version of Ruby. Here is my code

require 'logger'

class BankAccount
    attr_reader :file_logger, :stdout_logger

    def initialize(name)
        @name = name
        @transactions = []
        @logger = Logger.new(STDOUT)
        @file_logger = Logger.new("./bank_account.log")
    end

    def deposit(amount)
        log "Depositing #{amount}"
        @transactions.push(amount)
    end

    def withdraw(amount)
        log "Withdrawing #{amount}" ###logger.debug
        @transactions.push(-amount)
    end

    def log(message, level=Logger::INFO)
        file_logger.add level, message, "#{self.class} (#{@name})"
        stdout_logger.add level, message, "#{self.class} (#{@name})"
    end
end

account = BankAccount.new("Steven")
account.deposit(250)
account.withdraw(75)

It works fine in every version above 1.9 if you change line 9 to this:

@stdout_logger = Logger.new(STDOUT)
