Oracle doesn’t provide LTS updates. Each Oracle OpenJDK version is only supported for six months and doesn’t receive any further updates afterwards.

pretty sure you can get your openjdk lts updates from debian

Those are Debian's (or Redhat's, or Fedora's) builds.

Oracle ones are exactly as layer8 wrote. Moreso, if you also need windows or macos build; there's no Debian or Redhat then.

true!
