Logstash may fail to start under some circumstances. Single and double quotes are stripped from a pipeline configuration if the configuration includes environment or keystore variable references. If this situation occurs, Logstash may fail to start or some plugins may use a malformed configuration. Check out issue #16437 for details.
Workaround: Downgrade to Logstash 8.15.0, or temporarily avoid using environment and keystore variable references.

Logstash can fail to shut down under some circumstances when you are using Pipeline-to-pipeline communication. Check out issue #16657 for details.
Workaround: Add
-Dlogstash.pipelinebus.implementation=v1toconfig/jvm.options. This change reverts thePipelineBustov1, a version that does not exhibit this issue, but may impact performance in pipeline-to-pipeline scenarios.
