For new protocol consumer, if reconciliation happens during bouncing the brokers, `num_rebalances` will also be incremented. Currently there's no way to figure out whether a new rebalance is triggered or a reconciliation happens, so the assertion is skipped here. -- This is an automated message from the Apache Git Service.
