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.
