Description

Deploying test web service gives on JBoss startup:
Caused by: java.lang.ClassCastException: sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl cannot be cast to java.lang.reflect.TypeVariable
at org.apache.cxf.jaxb.JAXBContextInitializer.addType(JAXBContextInitializer.java:251)

Generated web service class has the following element which has issues with the JAXB binding:

@XmlElementRefs(

{ @XmlElementRef(name = "Salutation", namespace = "http://ws.gss.redhat.com/", type = JAXBElement. @XmlElementRef(name = "Name", namespace = "http://ws.gss.redhat.com/", type = JAXBElement.class) }

)
protected JAXBElement<String> [] salutationAndName;

Web service was generated from WSDL with <jaxb:globalBindings collectionType="indexed" /> and the following schema:

<xs:complexType name="Greetings">
<xs:sequence maxOccurs="unbounded">
<xs:element name="Salutation" type="xsd:string"/>
<xs:element name="Name" type="xsd:string"/>
</xs:sequence>
</xs:complexType>
