Temurin-build: AdoptOpenJDK 8u242 JIT enabled aarch32 build missing (Raspberry Pi)

@gdams - did we miss this in the latest release?

@karianna We are still missing JDK8/HS/arm32 (subject of this issue), JDK8/HS/aarch64 (I've been managing the resolution to a broken mirror for that one) and JDK13/HS/AIX

We enabled the JIT on arm32/JDK8/HS and need to properly go through the contents of https://github.com/AdoptOpenJDK/openjdk-tests/issues/1548 to ensure it's safe before looking to release that one.

Thanks for answering so quickly. Please post to this issue thread if there's something I can do to help. I have Pi Zero/Pi 2/Pi 3/Pi 4 platforms on which I can build/run tests.

We enabled the JIT on arm32/JDK8/HS and need to properly go through the contents of AdoptOpenJDK/openjdk-tests#1548 to ensure it's safe before looking to release that one.

Perhaps we could give @justinyunke an RC binary for him to test on his hardware?

I'm following up on AdoptOpenJDK/openjdk-tests#1548 - I'm personally OK with releasing this since it seems to be more about intermittent hardware failures than anything else.

Currently awaiting advice from @johnoliver on the mirroring since I can't build the JIT-enabled version at the correct level from our mirror of the source repository. If we can't get this resolved soon I might just release a non-JIT version again :'(

In the absence of an alternative solution being forthcoming I have reverted the build jobs back to using the main JDK8u repository and will attempt to push out an 8u242 without a JIT (Consistent with previous releases) ASAP

We've released 8u242 but without a JIT again as we can't easily build the GA level with JIT support unfortunately.

@karianna Since we haven't got a JIT-enabled GA JDK8/aarch32 build at the moment, the original problem description still stands, so I'm not sure it's appropriate to close this.

@sxa We can close this now correct? We have test failures, but there is a working binary?

We have a working binary since 8u272, yay!

$ jdk8u272-b10-aarch32-20201026/bin/java -version
openjdk version "1.8.0_272"
OpenJDK Runtime Environment (build 1.8.0_272-b10)
OpenJDK Client VM (build 25.272-b10, mixed mode)

What is the most efficient way to get this into the Raspberry Pi OS buster package repo to replace the currently-supported "stable 8u212-b01-1+rpi1?

If it's a matter of contacting the Raspberry Pi OS maintainers, I'll put in the effort if someone can give me a push. Here are the current results for "openjdk-8":

Let me see what I can do - it probably is worth persuing this now that we are fully operational with a JIT ... Didn't make much sense previously.

Our Debian repos work great on Raspbian. What's the problem apart from AdoptOpenJDK not being part of the official package feeds? And that's unlikely to change because Linux distributions usually do not accept binary packages and we cannot deliver anything else than binaries because of legal requirements.

Tried following the instructions on the AdoptOpenJDK page (https://adoptopenjdk.net/installation.html) to add the repo and got "Error: could not find a distribution template for Raspbian/buster". For the benefit of those that stumble upon this post, can you provide steps on how to add the Debian repo? I believe I tried this a while back and assumed it didn't work for Raspberry Pi OS (nee Raspbian) so I gave up.

If the instructions don't work for you (and I'll admit they didn't for me when I tried earlier today - we'll need to look at that) add this line to /etc/apt/sources.list, then run apt-get update as usual and you should be good to go I think:

deb https://adoptopenjdk.jfrog.io/adoptopenjdk/deb buster main

The apt-cache search adoptopenjdk to see what you can get from it

I've prepared a PR to improve the instructions for all the Debian and Ubuntu flavours: https://github.com/AdoptOpenJDK/openjdk-website/pull/842
