OpenJDK builds by Oracle are updated only for 6 months, even for LTS versions.
Plus these builds are provided for limited platforms only and have no official ready-to-use Docker images.
Well, I use those, because I uprade every 6 months.
And my company forces me to use theirs docker image and I put java on top of it.
BTW. Limited platforms, but covers most of the cases (64 bit linux, windows, mac plus aarch64 for linux and mac)
What do Docker images have to do with a JDK decision? Build your own image if you want.
Maybe if you read the page, you'll find out!
The rationale on the page is that the latest LTS version lags the latest release, which is expected and not a good reason to recommend against it.
