The JCK test jck test api/java_lang/foreign/VaList/Empty.html fails on Linux ppc64le with this exception (probably other platforms without handling in src/java.base/share/classes/jdk/internal/foreign/CABI.java might have the same issue):

looks like on this platform without support of foreign memory API the handling is still wrong.
