Document

Creates an ArrayList instance to hold estimatedSize elements, plus an unspecified amount of padding; you almost certainly mean to call #newArrayListWithCapacity (see that method for further advice on usage).

    }
    for (long l = min; l < max; l++) {
        result.add(l);
    }
    return result;
