Should I Upgrade?
Java 23 is end-of-life since 2025-03-18. Unless you have a commercial support contract for this version and a compelling reason to stay on the old version you should definitely upgrade to a newer version with active support.
There is no newer long term support LTS version than the version you're currently using. But you can upgrade to the latest regular release Java 24 which is currently maintained.
