Demystifying Spring Boot With Spring Debugger | The IntelliJ IDEA Blog Pull back the curtain on the Spring Boot magic and see how the Spring Debugger plugin makes the invisible visible.

The new Spring Debugger recently released by JetBrains is IMO a game changer in terms of DevXP, both for the Spring team and for Spring Boot application developers. blog.jetbrains.com/idea/2025/06...

Donald Knuth's "premature optimization is the root of all evil" was about micro-optimizations.

Designing your application to read and write data efficiently is not really premature optimization. It's software engineering.

For AssertJ 4, we wanted to upgrade to Java 17. However, we are discussing whether to stay on 8 or upgrade to 11.

The main reason is to keep our effort reasonable and continue supporting users who cannot upgrade yet (e.g., RHEL 7 users under ELS).

Any strong reason to keep upgrading to Java 17?

We just merged the current status of the upcoming JDWP support for @graalvm.org Native Image! 🥳

This will soon provide developers with the same debugging experience they are used to in Java, but for native images! Stay tuned for more details.
