> JAXB requires to explicitly configure the Unmarshaller to use the ObjectFactory using setProperty - it will otherwise use reflection (newInstance). An example:
> package test;
> @XmlRootElement
> @XmlType(name = "data")
> public class Data {
> }
> public class ExtendedData extends Data {
> }
> @XmlRegistry
> public class ObjectFactory {
>    public Data createData() {
>       return new ExtendedData();
>    }
> }
> public class Test {
>    public static void main(String[] args) throws Exception {
>       JAXBContext context = JAXBContext.newInstance(Test.class.getPackage().getName());
>       Unmarshaller u1 = context.createUnmarshaller();
>       String xml = "<?xml version=\"1.0\"?><data/>";
>       System.out.println(u1.unmarshal(new StringReader(xml)).getClass().getName());
>       Unmarshaller u2 = context.createUnmarshaller();
>       u2.setProperty(com.sun.xml.bind.v2.runtime.unmarshaller.UnmarshallerImpl.FACTORY,
>                new ObjectFactory());
>       System.out.println(u2.unmarshal(new StringReader(xml)).getClass().getName());
>    }
> }
> Output:
> test.Data
> test.ExtendedData
> To allow setting the above property JAXBDataBinding, JAXBEncoderDecoder and DataReaderImpl would require "unmarshallerProperties" (in line with existing marshallerProperties for the DataWriterImpl).
