[Roland Westrelin]

8u backport request. 6898462 was pushed to jdk9 on monday and it hasn’t caused any new failures during nightly testing. The change applies cleanly to 8u.

8067144 (currently a P4) is a follow up bug with TraceDeoptimization. It was pushed to jdk9 yesterday. It also applies cleanly to 8u.

Do we want it backported as well? I would say yes but I would need to bump it to a P3, right?
