Kernel.load with wrap=true does not protect the global namespace of calling program

      Description

      The rubydoc for Kernel#load explicitly states about the wrap parameter:

      "If the optional wrap parameter is true, the loaded script will be executed under an anonymous module, protecting the calling program's global namespace."

      But JRuby doesn't provide such protection at the moment.

      This caused one rubyspec failure:

      1)
      Kernel#load allows wrapping the code in the file in an anonymous module FAILED
      Expected "constant"
       to equal nil

      Attached also a standalone example that exhibits the problem. Run load_test.rb and you'll see:

      Z:\work\samples>ruby load_test.rb
      "main – 31095610"
      "MAIN: main – 31128780"
      nil
      nil

      Z:\work\samples>jruby load_test.rb
      "main – 18788761"
      "MAIN: main – 9102426"
      "constant"
      "constant"
