@Vassiliy-Kudryashov please investigate. May be we have changed something in Soot loading recently, so scanning dependencies is now longer that before. Also I suggest to rename read classes to scanning dependencies.

@Vassiliy-Kudryashov Could you please check. With the latest updates on main it takes minutes sometimes.
