If Immutant is dead, will take my lessons learned from the immutant-web perf fork and publish it as a clean slate separate lib under metosin - just a small wrapper for Undertow. Also not using the other parts of Immutant. Based on TFB, it's basically ~zero-penalty compared to the Java version: https://twitter.com/ikitommi/status/1133389851431264256 and will support both Promesa & Manifold out-of-the-box for async.
big thanks for writing Immutant @tcrawley & co, has been our go-to web server for years and have been reading & learning from it's source a lot . Sad to see it go, but we'll recreate something new & cool to fill the void. R.I.P.
wouldn't it be easier if someone became new maintainer of immutant instead of creating new?
