Re: Report NPE when client async request a non-exist URI

[jordan]

Hi Sergey,

Thanks for your quick repsonse and fix.

But I have apply in my env, it's not work for my code.

I downloaded from here and apply into my cxf jar file:
https://fisheye6.atlassian.com/browse/~raw,r=272b8533f84653a9da0d462600d64dd3c44829f3/cxf/rt/rs/client/src/main/java/org/apache/cxf/jaxrs/client/AbstractClient.java

Here is my code, it's simple:

public static void main(String[] args) throws Exception {
                String uri = 
"http://localhost:9081/jaxrs20App/rest/bookstore/delete";;
                Client c = ClientBuilder.newClient();
                c.register(new testFilter());
                WebTarget t1 = c.target(uri);
                Future<Response> future = t1.request().async().get();
                
                try{
                        future.get();
                } catch (Exception e){
                        System.out.println("I'm Exception!");
                }
                c.close();
        }

The *important *code is we register a testFilter:
public class testFilter implements ClientResponseFilter{
        @Override
        public void filter(ClientRequestContext arg0, ClientResponseContext 
arg1)
                        throws IOException {
                // TODO Auto-generated method stub      
        }
}

The exception also same:
java.lang.NullPointerException

        at java.lang.Thread.run(Thread.java:795)


So I think it's not work. You have tested this sample in you env. Thanks!
