Use 3 adapters, one to accumulate paketization units, another on to accumulate tiles and a last one to accumulate the final frame. Don't just blindly flush the adapter on DISCONT but only discard the current packetization unit. When we dropped jpeg2000 packets between SOP markers, adjust the SOT header with the new lenght.
