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?
