Description

java.lang.Long is not unmarshalled (while primitive long works)

Steps to reproduce:
1. Create a RPC-LITERAL web service on a stateless session bean with a single method like this:
public ResultDTO compute(FilterDTO filter)
FilterDTO must contain a java.lang.Long id; property.
Annotated FilterDTO with @XmlAccessorType(XmlAccessType.FIELD)

2. Generate the wsdl file with org.apache.cxf.tools.java2ws.JavaToWS

3. Deploy the ear by including the wsdl file also (wsdlLocation is specified on the bean for @WebService)

4. Start the server and use a client to call the method. Having RPC-LITERAL the parameter must be not null in the request.
So FilterDTO must be instantiated. Do not assign any value to the id field (let it null).

Result:
