I installed Logstash 5.5.1, 5.5.2 and even 6.0-beta1 bundled with another third party plugin to work with IBM JRE 8. The error "no cipher match" is thrown into logstash-plain.log. Per some deep investigation, this issue is relevant to JRuby-OpenSSL lib packaged with JRuby shipped with Logstash. Luckily, that issue ([https://github.com/jruby/jruby/issues/4679](https://github.com/jruby/jruby/issues/4679)) has been fixed in JRuby-OpenSSL 0.9.21, but Logstash was still delivered with old JRuby with old JRuby-OpenSSL version lower than 0.9.21. I checked Logstash 6.0-beta1, it includes Ruby-OpenSSL 0.9.20 gem. For Logstash 6.0-beta1, the log stack trace is here. All hosts unavailable, sleeping {:hosts=\>["xx.xx.xx.xx"], :e=\>#\, :backtrace=\>["org/jruby/ext/openssl/SSLContext.java:506:in `ciphers='", "org/jruby/ext/openssl/SSLContext.java:560:in`set\_params'", "/usr/share/logstash/logstash-core/lib/logstash/patches/stronger\_openssl\_defaults.rb:18:in `new'", "/usr/share/logstash/vendor/local_gems/dee1aeb2/logstash-output-mtlumberjack/lib/mtlumberjack/client.rb:215:in`block in connect'", "org/jruby/ext/thread/Mutex.java:148:in `synchronize'", "/usr/share/logstash/vendor/local_gems/dee1aeb2/logstash-output-mtlumberjack/lib/mtlumberjack/client.rb:154:in`connect'", "/usr/share/logstash/vendor/local\_gems/dee1aeb2/logstash-output-mtlumberjack/lib/mtlumberjack/client.rb:125:in `initialize'", "/usr/share/logstash/vendor/local_gems/dee1aeb2/logstash-output-mtlumberjack/lib/mtlumberjack/client.rb:76:in`connect'", "/usr/share/logstash/vendor/local\_gems/dee1aeb2/logstash-output-mtlumberjack/lib/mtlumberjack/client.rb:67:in `initialize'", "/usr/share/logstash/vendor/local_gems/dee1aeb2/logstash-output-mtlumberjack/lib/logstash/outputs/mtlumberjack.rb:143:in`connect'", "/usr/share/logstash/vendor/local\_gems/dee1aeb2/logstash-output-mtlumberjack/lib/logstash/outputs/mtlumberjack.rb:72:in `block in register'", "org/jruby/RubyRange.java:485:in`each'", "/usr/share/logstash/vendor/local\_gems/dee1aeb2/logstash-output-mtlumberjack/lib/logstash/outputs/mtlumberjack.rb:71:in `register'", "org/jruby/RubyArray.java:1734:in`each'", "/usr/share/logstash/logstash-core/lib/logstash/output\_delegator\_strategies/legacy.rb:17:in `register'", "/usr/share/logstash/logstash-core/lib/logstash/output_delegator.rb:41:in`register'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:376:in `register_plugin'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:387:in`block in register\_plugins'", "org/jruby/RubyArray.java:1734:in `each'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:387:in`register\_plugins'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:396:in `start_workers'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:321:in`run'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:281:in `block in start'"]} Is it possible for you to upgrade JRuby with 0.9.21 JRuby-OpenSSL inside Logstash 6.0? ---

[This change](https://github.com/jruby/jruby/pull/4726) you are requesting made it into [JRuby 9.1.13.0](http://jruby.org/2017/09/06/jruby-9-1-13-0.html), which should be incorporated into Logstash soon, as we need this version to address [JRuby 9000 instabilities](https://github.com/jruby/jruby/issues/4739) we [encountered during testing](https://github.com/elastic/logstash/issues/8006). Whether or not it makes it into the Logstash 6 release is still a matter of continued testing. It is certain, though, that we cannot use 9.1.12.0. We're still trying to determine whether we'll be able to move forward with 9.1.13.0. ---
