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: adapter_require.rb
    path of file: ./repos/activerecord-jdbc-adapter/lib/arjdbc/jdbc
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module ActiveRecord

  if defined? ConnectionAdapters::ConnectionHandler # 6.1
    ConnectionAdapters::ConnectionHandler
  elsif defined? ConnectionAdapters::ConnectionSpecification::Resolver # 4.0, # 5.x, # 6.0
    ConnectionAdapters::ConnectionSpecification::Resolver
  elsif defined? Base::ConnectionSpecification::Resolver # 3.2
    Base::ConnectionSpecification::Resolver
  else class << Base; self; end # 2.3, 3.0, 3.1 :

    def require(path)
      # NOTE: we're inspecting resolver.spec connection resolution which does :
      # `require "active_record/connection_adapters/#{spec[:adapter]}_adapter"`
      # ...
      # this {#require} method is only re-defined on a Resolver object and thus
      # will not hurt performance - it will only be called for a few times (most
      # likely once), this should still be fine for AR < 3.2 where this patch
      # ends up on `class << ActiveRecord::Base` since models usually rely on
      # Rails's auto-loading of (missing) constants and rarely use `require`.
      #
      # other alternative (to make sure we do not need to eager load AR built-in
      #  adapters) would be to mingle with the $LOAD_PATH which seems worse ...
