Does anyone know if there are any Debian (11 Bullseye) repositories providing the latest and greatest Java builds based on OpenJ9 or did someone perhaps write some scripts for automatically updating it from IBM's website?
AdoptOpenJDK as of Java 17 is dead, it is now rebranded as Adoptium (with a Hotspot-based Java build called Temurin to confuse everyone).
According to their FAQ they
- will no longer distribute OpenJ9-based builds
- their .deb repository is not yet up anyway
The only way of getting OpenJ9-based releases as far as I could find is getting the Semeru builds from IBM but they don't have a Debian repository, so you have to manually install the .tar.gz each time, which is a pain in the neck.
