Hi guys.
Today I attempting to upgrade LogStash OSS (OpenSearch Image opensearchproject/logstash-oss-with-opensearch-output-plugin) from version 8.4.0 to 8.6.1.
Everything looks good, I not spot any problems, but when LogStash starting, it generating strange warnings:
logstash /usr/share/logstash/vendor/bundle/jruby/2.6.0/gems/manticore-0.9.1-java/lib/manticore/client.rb:767: warning: already initialized constant Manticore::Client::KeyStore
logstash /usr/share/logstash/vendor/bundle/jruby/2.6.0/gems/manticore-0.9.1-java/lib/manticore/client.rb:705: warning: already initialized constant Manticore::Client::CertificateFactory
logstash /usr/share/logstash/vendor/bundle/jruby/2.6.0/gems/manticore-0.9.1-java/lib/manticore/client.rb:705: warning: already initialized constant Manticore::Client::CertificateFactory
logstash /usr/share/logstash/vendor/bundle/jruby/2.6.0/gems/manticore-0.9.1-java/lib/manticore/client.rb:456: warning: already initialized constant Manticore::Client::PoolingHttpClientConnectionManager
logstash /usr/share/logstash/vendor/bundle/jruby/2.6.0/gems/manticore-0.9.1-java/lib/manticore/client.rb:621: warning: already initialized constant Manticore::Client::AuthScope
It is a bug in LogStash itself and need to report it? Or have we problems somewhere in our configuration? (previous version not generate this warnings)
Thank you for your feedback!
