Narrative:

On a visual approach to boston 22L at about 1200 ft we got a false terrain warning. Aircraft was on the ILS; on the glideslope; on the VASI; over water and stabilized. Only thing I can think of is that we might have had a wrong altimeter setting. Radar altimeter showed over 1200 ft; don't recall what baro altimeter was showing.
