 Replying to [comment:5 breun]:
 > Looking at https://openjdk.org/projects/jdk/ it looks like the official
 repository is now on GitHub, so I think you should just replace
 https://git.openjdk.org/jdk8u/archive/refs/tags/ with
 https://github.com/openjdk/jdk8u/archive/refs/tags/

 Ideally one uses the facilities of the github portgroup for projects that
 are hosted on GitHub rather than implementing things manually.
