As monolith- and modular-based applications development has regained popularity, Spring has introduced a new experimental project, Spring Modulith, that supports developers in "expressing these logical application modules in code and in building well-structured, domain-aligned Spring Boot applications." InfoQ will follow up with a more detailed news story.

Andy Wilkinson, staff engineer at VMware, has announced that the Spring Initializr team will be changing their default build tool from Maven to Gradle. Wilkinson, on behalf of the team, is of the opinion that Gradle is a better build system, writing:

This is particularly true for Spring Boot 3.0-based applications where the developer experience with AOT processing is quite a bit better with Gradle. We'd like to nudge the community towards using Gradle while ensuring that Maven's only a click away for those that prefer it.

Developers who still prefer to use Maven can easily do so via https://start.spring.io/#!type=maven-project. InfoQ will follow up with a more detailed news story.

JavaOne

After a five-year hiatus, JavaOne returned to Las Vegas, Nevada, this past week at the Caesars Forum and Venetian Convention and Expo Center that featured many speakers from the Java community who presented and facilitated many session types such as Birds of a Feather, hands-on labs, lightning talks, tutorials and deep dives.

One of the many highlights was the Inside Java | JavaOne 2022 Technical Keynote. Facilitated by Chad Arimura, vice president, Java developer relations at Oracle, this keynote featured a number of special guests from Microsoft and Oracle.

  • Julia Liuson, president of developer division and GitHub at Microsoft, and Mark Heckler, principal Cloud developer advocate at Microsoft, presented ongoing Java development with Microsoft Azure.
  • Gavin Bierman, consulting member of technical staff at Oracle, discussed Project Amber and demonstrated how to use Record Patterns and Pattern Matching in switch.
  • Mikael Vidstedt, senior director, Java Virtual Machine, at Oracle, discussed ZGC.
  • Sean Mullan, consulting member of technical staff at Oracle, discussed Java security technologies.
  • Ron Pressler, consulting member of technical staff at Oracle, and Tomas Langer, architect at Oracle, discussed Project Loom and demonstrated how to use virtual threads in both blocking and reactive environments. Langer also introduced Helidon Níma, a new microservices framework based on virtual threads, that offers a low-overhead, highly concurrent server while maintaining a blocking thread model.
  • Denys Makogon, Java developer advocate at Oracle, presenting virtually from Ukraine, presented on how Project Loom and ZGC improved the team's telemetry ingestion engine for the Oracle Red Bull Racing F1 simulator.

The last JavaOne took place in 2017 before it was changed to CodeOne in 2018 and 2019. There were no conferences in 2020 and 2021 due to the pandemic.
