> All the methods in ReflectionUtils assume that Object is the superclass of every type and uses this condition to abort the walk of the type hierarchy. However, when an interface is passed in, the superclass is null, which causes these methods to throw a NullPointerException in the case the field or method is not found.
> Proper logic is:
> while (p != null && p != Object.class) {
>    ...
>    p = p.getSuperclass();
> }
