    Hi! Sorry for the late response!
    The intention of this condition is to prevent NPE or ClassCastException that may happen
in case `extractFromSetter()` fails or in case it returns some completely unexpected value.
    The unexpected value could happen from the unfortunate coincidence in which a getter exists
but it doesn't follow a Bean Property pattern. 
    Another possibility would be the property being overwritten by code outside cxf (That
should be unlikely, but it is possible) and therefore no longer a proxy.
