[Jersey] Re: Jersey nonblocking client issue

I already replied privately, but..

following testcase passes:

         final List<Object> l = new ArrayList<Object>();

         assertTrue(l.size() == 0);

         NonBlockingClient c = NonBlockingClient.create();
         c.addFilter(new ClientFilter() {
             @Override
             public ClientResponse handle(ClientRequest cr) throws
ClientHandlerException {
                 l.add(new String("before"));
                 final ClientResponse clientResponse = getNext().handle(cr);
                 l.add(new String("after"));

                 return clientResponse;
             }
         });

         WebResource r = c.resource(getUri().path("/").build());
         r.get(String.class);

         assertTrue(l.size() == 2);

can you share IWasHereFilter filter implementation?

Regards,
Pavel
