[~jcm] Flags used to generate java.base.so are the same as test is using. I think we missing Graal/AOT implementation for JDK-8191278. At least you need to implement in Graal setting as you did in C2: http://hg.openjdk.java.net/jdk/jdk/rev/3f3dc00a69a5#l21.1

probably because aot /graal doesn't set flag. may be test should be disabled for aot graal.
