Strange behavior of Module#attr_reader

If run this with ruby test.rb with MRI, Jruby, and in MRI irb: true

If run in Jruby irb: false

I think it can be related in following failing rails tests, but I'm not sure:

  3) Error:
AttrInternalTest#test_naming_format:
NoMethodError: private method `foo=' called for #<#<Class:0x64ea9235>:0x6af12899>
