Officially at least it seems that there are no post Java 8 JREs (or maybe Java 11 - I don't remember exactly) which is a shame. I know I can do it myself but having a small off the shelf runtime sure was convenient.
there is no "officially" anymore, java has gone open source with distributors kinda like linux distributions.
adoptium isn't the best distribution if you want to run on more than win/lin/mac x86_64.
