JDK-8287061 changed the format of ObjectValues in debug info but the SA wasn't updated. Additionally there are a couple of new types like MarkerValue, AutoBoxObjectValue and ObjectMergeValue which are unhandled. Decoding these values isn't critical to producing useful output so it might be worth treating decoding problems during decodeObjectValues as non-fatal. It's also missing JDK-8204209 which interferes with some cases for Graal.
