Yep, that's because concurrent stack processing (https://openjdk.java.net/jeps/376 https://openjdk.java.net/jeps/376) hasn't been merged yet, nor has the changes to the VM's internal references. Both of those are coming within a year. Until then, there's still significant work done by the GC at safepoints.
