Hi, I don’t understand what the exact problem is here. Have you had a build or a test failing that was not caught by GHA?
We build both fastdebug and release for all platforms that run tests. Take a look into any GHA run, for example, https://github.com/shipilev/jdk/actions/runs/17491480307 -- you can clearly see macos-(x64|aarch64) build (debug|release) jobs. What *is* awkward in current GHA configs: non-Hotspot tests are executed with release bits, while Hotspot tests are executed with fastdebug. So if you run fastdebug tier1 testing locally, it will not be 100% the same thing GHA runs. Arguably, we want to run all tests with fastdebug, really, but I never got to trying that in GHA. This would probably make tests slower. I am pretty sure GHA infra could handle it, it is only the question how much slower the testing would become. -Aleksey From: build-dev <build-dev-r...@openjdk.org> on behalf of "Baesken, Matthias" <matthias.baes...@sap.com> Date: Thursday, 11.

I checked the GHA settings from https://github.com/openjdk/jdk/blob/master/.github/workflows/main.yml And found that on Linux we build already (fast)debug. That’s good ! But seems we miss it on e.g. macOS and also Windows . Could we adjust the GHA settings or add a 3rd macOS build using (fast)debug ?
