I am attempting to upgrade LogStash OSS (OpenSearch Image
opensearchproject/logstash-oss-with-opensearch-output-plugin) from version 8.6.1 to 8.9.0
Everything looks good, upon LogStash start, it generates strange warning:
Sending Logstash logs to /usr/share/logstash/logs which is now configured via log4j2.properties
/usr/share/logstash/vendor/bundle/jruby/2.6.0/gems/sinatra-2.2.4/lib/sinatra/base.rb:938: warning: constant Tilt::Cache is deprecated
From what i understood, logstash is using an old version of sinatra (2.2.4) . The sinatra is using a Ruby feature that is now deprecated per https://github.com/sinatra/sinatra/blob/main/CHANGELOG.md.
Is it something we can ignore? Or It is a bug in LogStash itself and need to report it? (previous version did not not generate this warning)
Thank you !
