Hi there !

I'm very new to JRuby unit tests and I'm struggling a bit to run existing unit tests in [GitHub - logstash-plugins/logstash-integration-aws](https://github.com/logstash-plugins/logstash-integration-aws).

I've opened a PR to add a feature and would like to add some tests to validate my change, but first I'd like to have the existing ones passing.

I'm running Ubuntu 22.04  
I have `jruby 9.3.10.0 (2.6.8)` installed  
I have `rspec bundler rake` gems installed (using `sudo gem install`)  
`jruby -S bundle install` says `Bundle complete! 8 Gemfile dependencies, 82 gems now installed.`

but `jruby -S bundle exec rspec` fails with

```auto
LoadError:
  load error: jopenssl/load -- java.lang.NoClassDefFoundError: org/jruby/util/io/FileExistsException

# ./spec/spec_helper.rb:3:in `<main>'
# ------------------

# Java::JavaLang::ClassNotFoundException:
# org.jruby.util.io.FileExistsException
# java.base/java.net.URLClassLoader.findClass(URLClassLoader.java:476)
No examples found.

```

Does anyone know what I'm doing wrong or missing ?

Thanks !
