[dinogun]

AdoptOpenJDK now has musl libc based builds. Currently only for x64 arch. More info in this TSC issue

I feel the changes required include removing the download and installation of external GLIBC for hotspot images. Please lemme know if i had missed anything.

I think those musl builds only work for Java 16+ no? So not sure if this is a change for all Alpine containers.

musl is only >= 16 and x64.

From the TSC issue, Required work:

• Build and produce binary tarballs of 16 and newer on Alpine/x64 with musl build: add alpine musl builds adoptium/temurin-build#2026
• Mirror https://github.com/openjdk/portola into AdoptOpenJDK
• Create docker image for build/test ansible: add alpine build image adoptium/infrastructure#1496
• [] - Test 16 and newer on Alpine/x64
• [] - Add separate Docker images of Alpine/x64 with OpenJDK with musl (we already have a version with glibc)
• [] - Create APK for Alpine/x64
• [] - Create package repository for Alpine/x64 if the package cannot be integrated into Alpine's community repository
