APIPie cannot load in rails 4.2.8

[cshupp1]

Under JRuby 9.1.8.0 with rails 4.2.8 with the default apipie.rb:

Apipie.configure do |config|
  config.app_name = "RailsPrisme"
  config.api_base_url = "/api"
  config.doc_base_url = "/apipie"
  # where is your API defined?
  config.api_controllers_matcher = "#{Rails.root}/app/controllers/**/*.rb"
end

The following URL (http://localhost:3000/apipie) yields:

undefined method `reloader' for #<RailsPrisme::Application:0x158a8ca7> Did you mean? reloaders
