This Week in Spring - September 19th, 2023 (Java 21 Edition)

Engineering | Josh Long | September 19, 2023 | ...

Hi, Spring fans! Welcome to another installment of This Week in Spring - Java 21 edition!

The big news, indeed, the biggest news, is that Java 21 is now available here! You should use SDKMAN to install it, like this: sdk install java 21-graalce && sdk default java 21-graalce. This install givews you both the new Java 21 OpenJDK distribution and the new GraalVM native image support for Java 21. It works just fine with existing versions of Spring Boot, but the real payoff will be with Spring Boot 3.2, where you'll be able to plug in virtual threads with nary but a flick of a property: spring.threads.virtual.enabled=true. Spring Boot 3.2 drops in November. Get ready!
