Register multiple ClientResponseFilters, the execution order is random because the providerlist is HashMap?

[jordan]

Hi dear,

I'm using CXF client to access RS resource. And I register multiple
ClientResponseFilters for one client, but I see the execution order is
random, here is my code:

    public void testNew2ResponseFilter(Map<String, String> param,
StringBuilder ret) {
        String serverIP = param.get("serverIP");
        String serverPort = param.get("serverPort");

        ClientBuilder cb = ClientBuilder.newBuilder();
        Client c = cb.build();
*        c.register(ClientResponseFilter1.class);*
        WebTarget t1 = c.target("http://"; + serverIP + ":" + serverPort +
"/" + moduleName + "/ComplexClientTest/ComplexResource");
        *WebTarget t2 = c.target("http://"; + serverIP + ":" + serverPort +
"/" + moduleName +
"/ComplexClientTest/ComplexResource").register(ClientResponseFilter2.class);*
        Response res1 =
t1.path("echo1").path("test1").request().get(Response.class);
        Response res2 =
t2.path("echo2").path("test2").request().get(Response.class);
        System.out.println("config: " +
c.getConfiguration().getProperties());
        c.close();
        ret.append(res1.getStatus() + "," + res2.getStatus());
    }

I didn't set order number when I register the filters. So when I debug the
CXF code, I see if I didn't set order number for filter, CXF will set 5000
for ClientResponseFilter. And CXF will save filters to a provider list. But
this list is a HashMap (No order).... I'm not sure if can CXF change to
LinkedHashMap or other order list?

Here is the code in org.apache.cxf.jaxrs.impl.ConfigurationImpl:
private Map<Object, Map&lt;Class&lt;?>, Integer>> providers = 
        new HashMap<Object, Map&lt;Class&lt;?>, Integer>>(); 

I'm not sure if I understand correct. If no, could you please correct me if
anything I write wrong to make the filter execution non-order.

Thanks a lot! :)
