      In the constructor of G1RemSet the _prev_period_summary will be initialized if remembered set statistics tracking is enabled.

      This initialization accesses JavaThread::dirty_card_queue_set() on which the initialize() method has not been called yet.

      From what I understand this is a benign issue, but we have a bad case of initialization ordering dependency here.
