I’m very much looking forward to this fix! I’m using Kafka clients and Kafka Streams with JRuby — which works great with a “normal” JRuby app wherein you just run the code, but does not work once a JRuby project is packaged up into an “uber” JAR with a custom classloader. (Full details in this issue.)
