@theRealAph may wish to comment on this issue.

If ScopeValueAPI.java and ManyBindings.java are passing then it suggests that ScopeValue API is at least functional.  The JEP 429 implementation did have a small change to C2 (look at `git show 221e1a426070088b819ddc37b7ca77d9d8626eb4 src/hotspot/cpu`) and maybe the equivalent changes for s390x have not done been done yet.

Excluding the test via the ProblemList until the s390x work is done seem reasonable.
