      Description

      To reproduce the issue:
      1. wsgen -cp . wstest.EchoImpl against the following java file:
      package wstest;

      import javax.jws.WebMethod;
      import javax.jws.WebParam;
      import javax.jws.WebService;
      import javax.xml.ws.Holder;
      import java.rmi.RemoteException;
      import javax.jws.soap.SOAPBinding;

      @WebService
      @SOAPBinding(style=SOAPBinding.Style.RPC)
      public class EchoImpl {
          @WebMethod
          public String holderOperation(@WebParam(name="holder1", mode=WebParam.Mode.INOUT)Holder<String> holder1,
                                        @WebParam(name="holder2", mode=WebParam.Mode.INOUT)Holder<String> holder2) throws RemoteException{
              holder1.value += "1";
              holder2.value += "2";
              return "success";
          }
      }

      2. start the web service with the following java file:
      package wstest;

      import javax.xml.ws.Endpoint;

      public class EchoService {
          public static void main(String[] args) {
              Endpoint.publish("http://localhost:8080/WebServices/echoimpl", new EchoImpl());
          }
      }

      3. generate the client:
      wsimport -keep -p wstest.server http://localhost:8080/WebServices/echoimpl?wsdl

      4. run the client test with the following java file:
      import java.rmi.*;
      import javax.naming.*;
      import wstest.server.*;
      import javax.xml.ws.Holder;

      public class EchoClient {
          public static void main(String[] args) {
              EchoImplService service = new EchoImplService();
              EchoImpl port = service.getPort(EchoImpl.class);
              Holder h1 = new Holder("1");
              Holder h2 = new Holder("2");
              String result = port.holderOperation(h1, h2);
              
              System.out.println(result);
              System.out.println(h1.value);
              System.out.println(h2.value);
          }
      }

      Will get:
      null
      11
      22

      Note:
      1. Obviously some changes made the result better, now only the return value is null.
      2. If removing @SOAPBinding(style=SOAPBinding.Style.RPC) from EchoImpl java file or inserting a non-holder parameter at the first place in holderOperation method, it will have return value.
