(Occurs in 2.4 dev stream)

The following model:

@XmlRootElement(name="root")
public class Root {

	@XmlElementRefs({
			@XmlElementRef(name = "foo", type = Foo.class),
			@XmlElementRef(name = "bar", type = Bar.class)
		})
	public List content = new ArrayList();
}


@XmlRootElement(name="foo")
@XmlSeeAlso(SubFoo.class)
public class Foo {}


@XmlRootElement(name="subfoo")
public class SubFoo extends Foo {}


@XmlRootElement(name="bar")
@XmlSeeAlso(SubBar.class)
public class Bar {}


@XmlRootElement(name="subbar")
public class SubBar extends Bar {}


throws a JAXBException on marshalling (using Root.class as the context).

This works with the RI and generates an XML file of the form:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<root>
    <foo/>
    <subfoo/>
    <bar/>
    <subbar/>
</root>
