Hi Joel,

thank you for your input and very detailed explanation of the 
java-ecosystem and how the different vendors fit in it. I've read 
something about it when it all started a few years ago, but memory has 
faded since then.

Personally, I use the temurin builds by Adoptium on my windows 
development machines and I'm very happy with it. It's really great 
project and they keep on pushing stable and good builds for the 
opensource community. Especially the TCK compliance and the so called 
aquavit tests ensure that the builds are good and ready for production use.

I've thought about changing the aport builds from the plain openjdk 
build to the temurin build, especially as they provide a really good 
documentation and scripts to build the java versions from source.

But as far as I can see, they only provide alpine x86_64 builds and only 
headless builds. I'd like to provide builds for other arches as well 
(s390x, aarch64 and ppc64le) which seem to be not supported by temurin. 
Non-headless builds would also be nice but are not a game-breaker in my 

I've not decided yet which way we should take, to be honest. Both 
variants (building vanilla openjdk vs using temurin to build) have 
advantages and disadvantages.
Personally, I prefer staying as vanilla as possible, shipping exactly 
what oracle decides to ship with each release. But as you may see from 
the history of the openjdk11 aport in the git tree, I've had to do a lot 
of work to make it actually work with alpine and had to adjust the patch 
with each new version.
As oracle added the musl specific fixes and changes, it works quite well 
now and we just have to maintain a single, small patch for ppc64le only.
Also I think it's easier to write and adopt patches that way.

Do you see any advantages in using the build scripts from temurin over 
using the openjdk vanilla make?
