As mentioned in the bug it affects a rather old Docker release. Releases prior v18.4 (2019). It's been fixed in newer versions. So the question is how widespread is this? It must be systems where statx is available in the first place (kernel > 4.11 and glibc >= 2.28; systems not meeting the criteria won't use `statx`), but with the old docker version. There is a work-around to run the containers with the `--security-opt seccomp=<fixed_seccomp_profile.json>`.

JDK-8316304 adds birth time support on Linux. So that functionality will no longer be there if we back it out. Some users already rely on the feature, unfortunately. Either way we go somebody will be disappointed.
