foul on free throw

[bigwhistle]

Is this play specifically spelled out in the case book? I don't have my stuff with me.

A1 getting ready to attempt first shot of a 1 and 1. After he has received the ball from the official (therefore establishing team control for a brief time), and before he releases the ball on the free throw attempt, A2, located either on the free throw lane or outside the arc, commits a foul.

Does A1 get to attempt his free throw with the lane cleared or does the free throw attempt get nullified, which would be the case if A2 had violated instead of committed a foul?
