In my utility method:

public static <T> T getField(Object obj, Class c, String fieldName) {
    try {
        Field field = c.getDeclaredField(fieldName);
        field.setAccessible(true);
        return (T) field.get(obj);
    } catch (Exception e) {
        e.printStackTrace();
        fail();
        return null;
    }
}

The line

return (T) field.get(obj);

gives the warning "Type safety: Unchecked cast from Object to T"; but I cannot perform instanceof check against type parameter T, so what am I suppose to do here?
