Narrative:

GPWS terrain warning sounded while flying sjc JAWS1 arrival. Occurred during descent to 5000 ft on 300 degree heading after puckk intersection. Crew immediately responded with aggressive climb. Radar altimeter came alive during the maneuver, although exact altitude reached is unclr. Climbed until warning ceased and advised ATC of our actions. Leveled off at 7500 ft. IFR conditions prevailed throughout the event. Callback conversation with reporter revealed the following information: the reporter said that the captain was flying the aircraft and that they were descending at 2500 FPM and at 5500 ft they received a terrain warning. He said that the captain reacted quickly and started a maximum performance climb and he advised the controller. The controller answered after his second advisory and told him to turn to a heading and descend when they were clear. After landing, the reporter discussed the incident with members of the air carrier's flight department at sjc and was allegedly told that this has happened frequently there. The reporter said that may explain the controller's casual reaction to their climb reaction.
