I just tried it. It works for String-based properties. But not int, for example. Since unmarshalling/JAXB converts string values to the target Java types in metadata. And then the builder is called. One way to workaround this could be to make all the properties in the metadata Strings. It seems like whatever type of the property is the value is converted to String anyway during the service building. Also other uses of the unmarshalled metadata will have to be checked to make sure the system properties are substituted, e.g. when creating object names.
