Hi,

I found the root cause to this issue.

it occurring because of secure_compare method in
lib\ruby\gems\1.9.1\gems\activesupport-2.3.4\lib\active_support\message_verifier.rb

existing method in 2.3.4

  def secure_compare(a, b)
    if a.length == b.length
      result = 0
      for i in 0..(a.length - 1)
        result |= a[i] ^ b[i]
      end
      result == 0
    else
      false
    end
  end

to come out of this issue use below method, if you want.

  def secure_compare(a, b)
    result = a.length ^ b.length
    for i in 0..99 # or some other constant
      result |= a[i].to_i ^ b[i].to_i
    end
    result == 0
  end
