IBM's JVM used to support it at one stage, not sure if it still does or if other JVMs have picked it up.

- Freaky 3y agoIt appears to have a cool-sounding JIT server mode, allowing multiple clients to share a caching JIT compiler which does most of the heavy-lifting: https://www.usenix.org/conference/atc22/presentation/khrabrov https://www.usenix.org/conference/atc22/presentation/khrabro... https://developer.ibm.com/articles/jitserver-optimize-your-java-cloud-native-applications/ https://developer.ibm.com/articles/jitserver-optimize-your-j... It also has a "dynamic AOT compiler", so first-run stuff can be JITed and cached for future execution instead of it all starting out interpreted every time.
