----------------------------------------
One of the Rails CI, Active Job integration test with sidekiq, against Ruby 3.0.0 has been failing since August 30, 2020.

According to `git bisect` is is triggered by 2038cc6cab6ceeffef3ec3a765c70ae684f829ed . Somehow this issue only reproduces with Ruby on Docker like `rubylang/ruby:master-nightly-bionic`
It does not reproduce if Ruby is installed locally using `rbenv install 3.0.0-dev` on Ubuntu 20.04 and macOS 11 beta.

### The first failed build job

https://buildkite.com/rails/rails/builds/71321#84b29655-b3df-4b5c-8b20-cbf15ecd9653

``` ruby
Ruby          2.8.0p-1 (2020-08-29 revision d7492a0be885ea9f2b9f71e3e95582f9a859c439) [x86_64-linux]

```

### The last successful build job

```ruby
Ruby          2.8.0p-1 (2020-08-20 revision a74df67244199d1fd1f7a20b49dd5a096d2a13a2) [x86_64-linux]
```

### `git bisect` result

Performed `git bisect` ruby/ruby repository and it says `2038cc6cab6ceeffef3ec3a765c70ae684f829ed` triggers this build failure.

## Steps to reproduce

1. Install Docker
2. Install Ruby 2.7.1 (or whatever Ruby version to run rake)
3. Create Ruby docker image for 2038cc6cab6ceeffef3ec3a765c70ae684f829ed

```
git clone https://github.com/ruby/ruby-docker-images.git
cd ruby-docker-images
rake docker:build ruby_version=master:2038cc6cab6ceeffef3ec3a765c70ae684f829ed
```

4. Run Rails CI using the Docker image created in step 3

```
cd ~
git clone https://github.com/rails/rails.git
cd rails
git clone https://github.com/rails/buildkite-config .buildkite/
RUBY_IMAGE=rubylang/ruby:master-2038cc6cab6ceeffef3ec3a765c70ae684f829ed-bionic docker-compose -f .buildkite/docker-compose.yml build base && CI=1 docker-compose -f .buildkite/docker-compose.yml run default runner activejob 'AJ_ADAPTER=sidekiq AJ_INTEGRATION_TESTS=true bin/test test/integration/queuing_test.rb --seed 5170'
```

## Actual result

```

Run options: --seed 5170

## Expected result

It should success as the Ruby as of the previous commit `1035a3b202ee86bf2b0a1d00eefcfff0d7ab9f6b` does.
