Description Karen Butzke CLA 2010-12-10 13:22:41 EST 
Given this example MOXy hits the following exception processing the annotations. It is because of the return type of JAXBElement not having any type arguments.

     class Pea {
         @XmlElementRefs({
             @XmlElementRef(name="foo",type=JAXBElement.class)
             @XmlElementRef(name="bar",type=JAXBElement.class)
         })
         List<JAXBElement<String>> fooOrBar;
     }
 
     @XmlRegistry
     class ObjectFactory {
         @XmlElementDecl(scope=Pea.class,name="foo")
         JAXBElement createPeaFoo(String s);
 
         @XmlElementDecl(scope=Pea.class,name="bar")
         JAXBElement createPeaBar(String s);
 
         @XmlElementDecl(name="foo")
         JAXBElement createFoo(Integer i);
     }

Comment 2 Blaise Doughan CLA 2010-12-14 14:11:00 EST 
Fix checked into trunk at rev:  8706

MINOR CHANGE:
Guard against there being no type parameter on the JAXBElement by returning Object.class.
