The way you can get around this is to create a generic method and do the 'routing' inside that method. I know that this might not be ideal, but you end up with less configurations in functions and XHTML pages.

if (A.class.isInstance(obj)) {
    A o = (A) obj;
    return method(o, highRes);
} else if (B.class.isInstance(obj)) {
    B o = (B) obj;
    return method(o, highRes);
} else if (C.class.isInstance(obj)) {
    C o = (C) obj;
    return method(o, highRes);
} else {
    throw new FacesException("Unsupported Conversion: " + obj);
}
