This pull request does not have a backport label. Could you fix it @donoghuc? 🙏
To fixup this pull request, you need to add the backport labels for the needed
branches, such as:

backport-8./d is the label to automatically backport to the 8./d branch. /d is the digit.
If no backport is necessary, please add the backport-skip label

TL;DR

The current Buildkite failures are caused by the newly-pinned jrjackson 0.5.1 gem loading incorrectly: require "logstash/json" fails because jrjackson-0.5.1-java/lib/jrjackson/jrjackson.rb requires jrjackson_jars, but the installed gem does not include lib/jrjackson_jars.rb. This is different from the earlier 0.5.0.1 unavailable-gem failure; 0.5.1 resolves, but cannot load.

Remediation

Fix/re-release the upstream jrjackson 0.5.1 Java gem so it includes the generated lib/jrjackson_jars.rb loader expected by lib/jrjackson/jrjackson.rb:6, or temporarily pin Logstash back to a loadable jrjackson version.
After the gem is fixed or the pin is changed, rerun ./gradlew --no-daemon :logstash-xpack:rubyTests --tests org.logstash.xpack.test.RSpecTests and the x-pack integration step.

Investigation details

Root Cause

This PR pins jrjackson: 0.5.1 in versions.yml:30, and logstash-core/logstash-core.gemspec:79 consumes it as an exact runtime dependency:

gem.add_runtime_dependency "jrjackson", "= #{ALL_VERSIONS.fetch('jrjackson')}" #(Apache 2.0 license)

With that gem installed, Logstash's JSON wrapper loads jrjackson from logstash-core/lib/logstash/json.rb:19. The gem then fails at vendor/bundle/jruby/3.4.0/gems/jrjackson-0.5.1-java/lib/jrjackson/jrjackson.rb:6:

require "jrjackson_jars"

The installed jrjackson-0.5.1-java gem contains the Jackson jars and lib/jrjackson/jars/jrjackson-1.3.0.jar, but does not contain the required lib/jrjackson_jars.rb file, so every x-pack spec that loads logstash/devutils/rspec/spec_helper or logstash/agent fails during file load before examples run.

Evidence

Build: https://buildkite.com/elastic/logstash-pull-request-pipeline/builds/5030
Failed jobs: :lab_coat: x-pack unit tests and :lab_coat: x-pack integration
Buildkite summary logs show RSpec load-time failures, not assertion failures:

0 examples, 0 failures, 19 errors occurred outside of examples
...
Execution failed for task ':logstash-xpack:rubyTests'.
> There were failing tests.

0 examples, 0 failures, 12 errors occurred outside of examples
...
Execution failed for task ':logstash-xpack:rubyIntegrationTests'.
> There were failing tests.

Local reproduction on commit eaad695e4931610b9eb293fe8e2431d69d721202 produced the missing loader error:

LoadError: cannot load such file -- jrjackson_jars
  <main> at .../vendor/bundle/jruby/3.4.0/gems/jrjackson-0.5.1-java/lib/jrjackson/jrjackson.rb:6
  <main> at .../vendor/bundle/jruby/3.4.0/gems/jrjackson-0.5.1-java/lib/jrjackson.rb:2
  <main> at .../logstash-core/lib/logstash/json.rb:19

Verification

GRADLE_USER_HOME=/tmp/gh-aw/agent/gradle-home ./gradlew --no-daemon bootstrap succeeds, confirming the old unresolved-gem blocker is gone for 0.5.1.
GRADLE_USER_HOME=/tmp/gh-aw/agent/gradle-home ./gradlew --no-daemon :logstash-xpack:rubyTests --tests org.logstash.xpack.test.RSpecTests --stacktrace reproduces the x-pack failure locally with LoadError: cannot load such file -- jrjackson_jars.
bin/ruby -Ilogstash-core/lib -e 'require "logstash/json"; puts LogStash::Json.dump({"ok"=>true})' reproduces the same minimal load failure.
Checked the installed gem contents and confirmed vendor/bundle/jruby/3.4.0/gems/jrjackson-0.5.1-java/lib/jrjackson_jars.rb is absent.
