This is an auto-filled bug because dev-java/openjdk-jre-bin installs files with broken symlink. The issue was originally discovered on amd64, but it may be reproducible on other arches as well. If you think that a different summary clarifies the issue better, feel free to change it. Attached build log and emerge --info.

symlink is correct after it's installed, but incorrect at the time of check, because it's relative. So either QA check needs to be fixed or CI warnings that require to use relative symlinks all the time need to be relaxed. I'd prefer to link directly to ${ROOT}/etc/ssl/certs/java/cacerts instead of this multi-layer madness in the ebuild ( ../../../../ )
