Presumably, findFaces() gets called for each image.  In the fixed version,
the Vector gets cleared at the start of each call.  In the broken one, for
the second image, "do stuff to populate the faces Vector" begins with the
Vector left over from the first image.  This might be a problem if the
Vector contains references to the first ImageProcessor, and these references
are somehow applied to the second ImageProcessor in "do stuff".
