capybara: Crash on jruby due to matcher proxies hitting a jruby bug

Hello! 👋 👋

So, I upgraded the activeadmin’s spec environment to use latest capybara and specs on jruby started failing. I bisected the issue to df010d79a5c7b3418b67e1aabd570d62036f4f29. My guess is that it is due to https://github.com/jruby/jruby/issues/4678. Reverting the mentioned commit fixes the issue. I would suggest that we revert to the old solution not using prepend only on jruby until the upstream issue is fixed. I could provide a patch if you want.

Expected Behavior

Specs work just like on MRI.

Actual Behavior

bundle exec rspec spec/sample_spec.rb 
/home/deivid/Code/playground/test_app_jruby/db/schema.rb doesn't exist yet. Run `rails db:migrate` to create it, then try again. If you do not intend to use a database, you should instead alter /home/deivid/Code/playground/test_app_jruby/config/application.rb to limit the frameworks that will be loaded.

rspec ./spec/sample_spec.rb:11 # 4 should not be a multiple of 3

Steps to reproduce

Make sure you’re using jruby. Then,

$ rails new test_app_jruby
$ bundle add capybara --group test
$ bundle add rspec-rails --group development
$ bundle add listen --group development # bug in Rails, generator on jruby does not add it by default by it's needed
$ rails g rspec:install
$ echo "                             
require 'rails_helper'

RSpec::Matchers.define :be_a_multiple_of do |expected|
  match do |actual|
    actual % expected == 0
  end
end

RSpec.describe 4 do
  it { is_expected.to_not be_a_multiple_of(3) }
end
" > spec/sample_spec.rb
$ bundle exec rspec spec/sample_spec.rb

@deivid-rodriguez Ok – could you try the jruby_prepend_super branch and see if that fixes your issue?. You’ll probably need to require 'capybara/rspec/matcher_proxies before requiring RSpec in your spec_helper
