The effect of wake turbulence is related to the relative sizes of the planes involved. A wake which could roll a small plane over may feel like a small bump on a plane of equal size. While not as large as the JAL 747, the A300 is not a small plane, and 2 minutes spacing is usually enough to remove ALL wake effects from the next departing plane.

Well, some reports and data indicate that in the air, their paths were as little as 45 seconds apart. To be confirmed.
