You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: test_drbssl.rb
    path of file: ./repos/jruby/test/mri/drb
    
    the code of the file until where you have to start completion: # frozen_string_literal: false
require_relative 'drbtest'

begin
  require 'drb/ssl'
rescue LoadError
end

module DRbTests

if Object.const_defined?("OpenSSL")


class DRbSSLService < DRbService
  %w(ut_drb_drbssl.rb ut_array_drbssl.rb).each do |nm|
    add_service_command(nm)
  end

  def start
    config = Hash.new

    config[:SSLVerifyMode] = OpenSSL::SSL::VERIFY_PEER
    config[:SSLVerifyCallback] = lambda{ |ok,x509_store|
