Here’s the diff I have at the moment. This is not an exhaustive list of extensions with no JRuby support but it’s most of them. > Some replacements I know of: - fast\_xor has been superceded by xorcist, which has JRuby support. - pg has a JRuby equivalent in pg\_jruby. It lags behind pg a lot (lack of resources). - oj may have JRuby support soon; Tom Enebo has a partial port. - cppjieba\_rb might be extended to support JRuby using the jieba-analysis Java library. I have started a dialog with the author here: [JRuby support using jieba-analysis library for Java · Issue #1 · erickguan/cppjieba\_rb · GitHub](https://github.com/fantasticfears/cppjieba_rb/issues/1) - fast\_blank (transitive dependency of onebox) was trivial to port to JRuby. My PR is here: [JRuby support by headius · Pull Request #21 · SamSaffron/fast\_blank · GitHub](https://github.com/SamSaffron/fast_blank/pull/21) - Presumably unicorn can just be replaced with puma. Both are in the Gemfile. Other exts will have to be discussed. --- _[View the full topic](https://meta.discourse.org/t/getting-discourse-running-on-jruby/81273)._
