NPE in order line detail when supplychain is disabled

Line 134 in a3fab02

(boolean) initAvailabilityRequest(saleOrderLine).get("$availabilityRequest");

initAvailabilityRequest returns an empty map
initAvailabilityRequest(saleOrderLine).get("$availabilityRequest") returns null
(boolean) initAvailabilityRequest(saleOrderLine).get("$availabilityRequest") throws a NPE

Am I missing something ?
