Myapp :: Application :: There is no permanent connection with Rails 4 beta and Jruby jruby-1.7.2

I could not get jruby to work with Rails 4 without hacking:

In railties / lib / rails / engine.rb I had to initialize Railties with const_get, otherwise

def railties @railties ||= self.class.const_get(:Railties).new # @railties ||= self.class::Railties.new end

Otherwise, I get the following:

./ben/ Rake rake interrupted! uninitialized constant Myapp :: Application :: Railties org / jruby / RubyModule.java: 2677: in const_missing' /Volumes/Opt/rails/rails-edge/railties/lib/rails/engine.rb:469:in railties' / Volumes / Opt / rails / rails -edge / railties / lib / rails / application.rb: 241: in run_tasks_blocks' /Volumes/Opt/rails/rails-edge/railties/lib/rails/engine.rb:444:in load_tasks' org / jruby / RubyBasicObject.java: 1659: in __send__' org/jruby/RubyKernel.java:2086:in send' / Volumes / Opt / rails / rails -edge / railties / lib / rails / railtie / configurable.rb: 30 : in method_missing' /Volumes/Opt/projects/myapp/Rakefile:6:in (root)' org / jruby / RubyKernel.java: 1046: in `load '

Rails itself does not start for the same reason. Is this the correct fix or am I masking some basic issues?

Actually the problem is not solved, but I added

 Rails::Engine.class_eval do def railties @railties ||= self.class.const_get(:Railties).new end end

under Bundler.require in application.rb so as not to change the source files.

It seems that this fix was fixed in the Rails host (a small change for the engine): https://github.com/rails/rails/commit/45aabe61520cbb4bd74f6de7dc1023d2ca071e40

I just added:

 gem 'rails', :git => 'git://github.com/rails/rails.git'

or simply

 gem 'rails', github: 'rails/rails'

to my gemfile to pull out the latest version of Rails, and that did the trick. I managed to remove Alex (nice - thankyou!) Hack, and everything works as it should.
