Narrative:

During taxi out, we received clearance to cross runway 15 at taxiway juliet for a runway 19 departure. Realizing an aircraft in position on runway 15 had started its takeoff roll, we stopped our aircraft prior to the hold line for runway 15 and questioned the clearance to cross runway 15. Ground acknowledged the error they made.
