Oracle has released the production version of Helidon 4, a microservices framework for Java featuring a server implementation harnessing virtual threads for higher performance.
Version 4 was announced October 24; instructions can be found at helidon.io. There also is a migration guide. Before Helidon 4, the project’s web server utilized Netty as its foundation and used a reactive API. Release 4 introduces a new server, internally called Nima, designed to harness the capabilities of Java 21 virtual threads.
