JAXB-ElipseLink: Marshaller не проверяет

Я не смог воспроизвести проблему, которую вы видите. Ниже приведено то, что я пробовал (адаптировано из следующего сообщения в блоге):

MarshalDemo (адаптировано из записи в блоге)

import java.io.File;
import javax.xml.XMLConstants;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.stream.XMLOutputFactory;
import javax.xml.stream.XMLStreamWriter;
import javax.xml.validation.Schema;
import javax.xml.validation.SchemaFactory;

import org.eclipse.persistence.Version;

public class MarshalDemo {

    public static void main(String[] args) throws Exception {
        Customer customer = new Customer();
        customer.setName("Jane Doe");
        customer.getPhoneNumbers().add(new PhoneNumber());
        customer.getPhoneNumbers().add(new PhoneNumber());
        customer.getPhoneNumbers().add(new PhoneNumber());

        SchemaFactory sf = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI); 
        Schema schema = sf.newSchema(new File("src/blog/jaxb/validation/customer.xsd"));

        JAXBContext jc = JAXBContext.newInstance(Customer.class);
        System.out.println(jc.getClass());
        System.out.println(Version.getVersion());

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.setSchema(schema);
        marshaller.setEventHandler(new MyValidationEventHandler());
        XMLStreamWriter xsw = XMLOutputFactory.newFactory().createXMLStreamWriter(System.out);
        marshaller.marshal(customer, xsw);
    }

}

Вывод
