I don't read it that way at all. The javadoc says: "...then the copying is performed AS IF [my emphasis] the components at positions srcPos through srcPos+length-1 were first copied to a temporary array..." Reallocation is _not_ necessary when implementing arraycopy, just care in handling the overlap cases.
