Given the following annotations:

@XmlElements({@XmlElement(type=Integer.class), @XmlElement(type=Float.class)})
@XmlPaths({@XmlPath("integers/@my-integer"), @XmlPath("floats/my-float/text()")})
public Object thing;

We will get the following exception during JAXBContext creation:

javax.xml.bind.JAXBException:
