Can't run my rspec test with jRuby and Rails 4.1.4.

I have a Rails application (4.1.4) running with jRuby 1.7.15 (1.9.3p392) 2014-09-03 82b5cc3 on Java HotSpot(TM) 64-Bit Server VM 1.7.0_67-b01.

You can see my Gemfile at: http://ift.tt/1FTGsn5.

My Gemfile.lock: http://ift.tt/1GTsvln.

As you can see I'm using rspec (2.14.1) and rspec-rails (2.14.2).

I have a user_spec.rb file something like this:

require 'spec_helper'

describe User do
  include_context "stubbed organization"
  subject { build_stubbed(:super_admin, organization: organization) }
  let(:notification_queue) { build_stubbed(:notification_queue) }

  before(:each) do
    allow(NotificationQueue).to receive(:find_each)
  end
  it "has name assigned" do
    user = build(:member, first_name: 'John', last_name: 'Smiths')
    expect(user.first_name).to eq('John')
    expect(user.last_name).to eq('Smiths')
  end

  it "has a first name" do
    subject.first_name = nil
    expect(subject).not_to be_valid
  end

  it "has a last name" do
    subject.last_name = nil
    expect(subject).not_to be_valid
  end

end

and once I run the test I get the following results:

⇒  rspec spec/models/user_spec.rb
