New GraalVM project Crema now supports runtime class-loading. Here's a full Clojure runtime built with GraalVM native-image + Crema: https://github.com/borkdude/cream

Modern java (check this - https://www.infoq.com/articles/data-oriented-programming-jav... ) is really not that bad. Golang is like far more verbose than even JDK 8 (9 old release) …

Yes, IMO game changing for java. Read this JEP - https://openjdk.org/jeps/425 Here is a simple echo server running on Virtual thread (using same old blocking APIs, handle 5m persis…

Check compose mpp, uses Kotlin and Skia under the hood. Really good performance overall. https://www.jetbrains.com/lp/compose-mpp/

May be by next LTS (java 21 - 2023 Sep) :D

Yes, nerdctl compose will work for most of the use cases. Check this compatibility guide - https://github.com/containerd/nerdctl/blob/master/docs/compo...

JDK is modular now and ecosystem is moving towards jlinked application. So no need for jdk on the target machine.

Probably once ZGC gets the generation support ( https://github.com/openjdk/zgc/tree/zgc_generational ) which will reduce the memory footprint.

jfyi: here is the latency GC numbers (JDK17) - https://kstefanj.github.io/2021/11/24/gc-progress-8-17.html . The experience is vastly different compared to an 8 year old jdk versio…

That's case for virtual threads also. It uses ForkJoinPool.ManagedBlocker to add additional threads. "File I/O is problematic. Internally, the JDK uses buffered I/O for files, whic…

Yeah that decision make sense for multi platform. Suspending functions will work on JS and Kotlin Native.

Is this the case very large go heaps? ZGC claims sub ms pause for TB heap size.
