Javelin Pilot's Notes (FAW Mk 7) provide:
If the aircraft has not stopped spinning or is stalled at or below 15,000 feet above the ground it should be abandoned.
(f) Stall with flaps and undercarriage down
Tunnel and model tests show that the aircraft should not spin in this condition, but once stalled the only likely method of recovery is to raise the flaps and undercarriage. The aircraft will then probably spin, and recovery as above should be taken. The stalling speed with flaps down is about 90 to 95 knots.
