com/sun/jmx/remote/NotificationMarshalVersions/TestSerializationMismatch.java with -Xcomp -XX:CompileThreshold=100 -XX:+VerifyOops fails fairly reliably with Graal on linux-aarch64. The G1WriteBarrierSnippets include some verifyOops paths with -XX:+VerifyOops and it's likely there is some register saving problem there.
