@kstefanj Thanks! Draft of changes requested here. Any comments/suggestions are appreciated.

😕 Maybe a bug got through to main branch, but I can't build locally after master merge. Error coming from G1GCPhaseTimes::log_phase. So I wasn't able to run some tests locally. Pushed to see if it builds and passes tests form github actions env.
