      Description

        Currently we measure the duration of the strong roots processing in a single phase called "Ext root scan". This phase consists of a lot of different tasks: it would be convenient if we had a per-phase/per-thread breakdown for this to spot imbalances and other issues in this phase.

        Improve this logging for at least the G1 collector.
