ClientProxy throws NullPointerException when invoking its invoke()

[nereuschen]

hi,all:
  
ClientProxy throws NullPointerException when invoking its invoke();

java version : jdk1.6.0_30
cxf version :2.6.2 ,2.7.0,2.7.3 

I debug the code  and find the ClientProxy.finalize() closes the bus ,so the
bus is null ,then when the ClientImpl  to invoke the method doInvoke(),it 
throws NullPointerException

the exception is:

The Sever works fine.
step1:  To run the class demo.hw.server.Server.java 


public class Server {

    protected Server() throws Exception {
        HelloWorldImpl helloworldImpl = new HelloWorldImpl();
        ServerFactoryBean svrFactory = new ServerFactoryBean();
        svrFactory.setServiceClass(HelloWorld.class);
        svrFactory.setAddress("http://localhost:9000/Hello";);
        svrFactory.setServiceBean(helloworldImpl);
        //svrFactory.getServiceFactory().setDataBinding(new
AegisDatabinding());
        svrFactory.create();
    }

    public static void main(String args[]) throws Exception {
        new Server();
        System.out.println("Server ready...");

        Thread.sleep(500 * 60 * 1000);
        System.out.println("Server exiting");
        System.exit(0);
    }
}

 
But the client failed,it throws a NullPointerException 

step2: to run the client  demo.wsdl2java.Demo.java,it throws a
NullPointerException  


public class Demo {

    protected org.apache.cxf.endpoint.Client initClient() {

        int connectTimeout=10;
        int receiveTimeout=60;

        HelloWorld helloWorld = new HelloWorld();
        HelloWorldPortType port = helloWorld.getHelloWorldPort()                
    
;

        org.apache.cxf.endpoint.Client client = ClientProxy.getClient(port);
//        HTTPConduit httpConduit = (HTTPConduit) client.getConduit();
//        HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
//        //httpClientPolicy.setConnectionTimeout(connectTimeout);
//        httpClientPolicy.setAllowChunking(false);
//        //httpClientPolicy.setReceiveTimeout(receiveTimeout);
//        httpConduit.setClient(httpClientPolicy);
//        client.getInInterceptors().add(new LoggingInInterceptor());
//        client.getOutInterceptors().add(new LoggingOutInterceptor());
        return client;
    }

    public void invokeByClientProxy(){
        System.out.println("invoke initClient...");
        Client client=   this.initClient();
        System.out.println("invoke sleep...");
        Object[] result= new Object[0];
        try {
            result = client.invoke("sleep",0L);
        } catch (Exception e) {
            e.printStackTrace();  //To change body of catch statement use
File | Settings | File Templates.
        }
        client.destroy();
        System.out.println("PRINT RESULT...");
        for(int i=0;i<result.length;i++){
            System.out.println(result[i]);
        }
    }

    public void invoke(){
       QName SERVICE_NAME = new QName(&quot;http://server.hw.demo/&quot;,
&quot;HelloWorld&quot;);
        URL wsdlURL = HelloWorld.WSDL_LOCATION;
        HelloWorld ss = new HelloWorld(wsdlURL, SERVICE_NAME);
        HelloWorldPortType port = ss.getHelloWorldPort();

        {
            System.out.println(&quot;Invoking sleep...&quot;);
            long _sleep_arg0 = 0;//60*1000+200;
            java.lang.String _sleep__return = port.sleep(_sleep_arg0);
            System.out.println(&quot;sleep.result=&quot; + _sleep__return);
        }
    }

    public  static  void main(String[] args) throws Exception {
        Demo demo = new Demo();
       demo.invokeByClientProxy();
     //  demo.invoke();

     //   Thread.sleep(100000);
    }
}
