• interestingly this only happened for the non-jacoco builds, which indicates that the AOT cache for these was only corrupted
  • It's likely that a corrupted AOT was created by https://github.com/xdev-software/tci/actions/runs/29089281811/job/86350476712
• The first warnings can be ignored due to https://bugs.openjdk.org/browse/JDK-8364929
• The error looks similar to the one described here: https://www.coffeesprout.nl/en/quarkus-jdk25-aot-cache-cpu-mismatch.html
• Clearing the cache with gh cache delete --all fixed the problem

Todo:

• Try to reproduce the error
• Report the bug
  • Adoptium: Launching with AOT cache fatally crashes with SIGILL (0x4) depending on available CPU instructions adoptium/adoptium-support#1507
  • Report it to OpenJDK → Investigate SIGILL (0x4) in AdapterBlob #688 (comment)
• Build a utility to automatically detect and read hs_err_pid*.log files
• Implement workaround

[AB-xdev]

Can confirm the observed behavior from the article.

Steps to reproduce:

1. Run tests on a AVX512 machine (e.g. Zen4+ CPU)
2. Export the image using docker save tci-demo-webapp > tci-demo-webapp-avx512.tar
3. Copy it over to non AVX512 machine
4. Import the image using docker load -i tci-demo-webapp-avx512.tar
5. Run the tests and replace the image builder with the docker image name ("tci-demo-webapp")

Bug was opened at https://bugs.openjdk.org/browse/JDK-8388703

[AB-xdev]

As described in adoptium/adoptium-support#1507 (comment) the problem can be worked around by using:

• -XX:+UnlockDiagnosticVMOptions -XX:-AOTAdapterCaching during training/creation or runtime
• -XX:UseAVX=2 during training/creation

The problem seems to be fixed on JDK 27 with https://bugs.openjdk.org/browse/JDK-8381975 however that's no LTS or released yet.

As described in adoptium/adoptium-support#1507 (comment):

The bugfix was merged and will become available with JDK 25.0.5 (October 2026).
