If hadoop did it, so can you. I'm talking about a project that stretched Java 8 to, and arguably beyond, its intended operational boundaries. Unlikely that you’re leaning on this boundary. It's Spring Boot upgrades that will be giving you troubles.

Mostly an automatic updater call (for javax->jakarta) and a few dependency bumps away in the majority of cases.
Plain vanilla java code is really backwards compatible, on both a syntax, and on a binary level.
You can often find decades old jars on some random university site, working with JDK 25 with no issue.
