Does this issue qualify for a bug ?

Yes, I did it many times.
With 200 threads it still worked fine.
With 500 some requests failed...
no idea what the problem is...

I have created new Instance for each thread but still I have the same issue.

RestClient client = new RestClient();

for ( int i =0; i < 50 ; i ++ ){
             resource = client.resource("http://localhost:8080/logger/test");
             new Thread(new Multi(resource),new Integer(i).toString()).start();

If I understand your code correctly, you reuse Resource instance on multiple threads.
But as I recall Resource is not threadsafe.
Just create a new instance each time, and it should be fine.

Hi
I am requesting  Concurrent requests to a Resource.
But on the Resource, bean objects are not completely populated for some request and gets populated
completely for other requests.

Please see the Client,Bean and Resource Class below.

For few client request the request.getSelectedOptions() always returns null .

Is this a bug with Wink ?

Can you please help

Client

class Multi implements Runnable{
    Resource resource;
    String xml = "<UserSubscription>"
            +       "<selectedOptions><entry><key >Amount of Memory (MB)</key><value

                                           "<entry><key>Number of CPUs</key><value>1</value></entry>"
+
                                           "<entry><key>Number of Servers</key><value>1</value></entry>"
            +      "</selectedOptions>"
            +   "</UserSubscription>";

    Multi(Resource resource){
        this.resource = resource;

    }
    public void run(){
             String res = resource.contentType(MediaType.APPLICATION_XML).accept(MediaType.TEXT_PLAIN).post(String.class,xml);
             System.out.println("thread - " + Thread.currentThread().getName() + " : " + 
res);
    }
}

Bean Class

@XmlAccessorType(XmlAccessType.NONE)
@XmlRootElement(name = "UserSubscription")
public class ServiceRequest {
                private Properties modelInputs;


                public  void setSelectedOptions(Properties modelInputs) {
                                this.modelInputs = modelInputs;
                }

                @XmlElementWrapper(name = "selectedOptions", required = true, nillable = false)
                public  Properties getSelectedOptions() {
                                return this.modelInputs;
                }
}


Resource Class

@Path("/test")
public class PropResource {

@POST
@Consumes(MediaType.APPLICATION_XML)
@Produces(MediaType.TEXT_PLAIN)
    public Response getLogs(ServiceRequest request){

    String res = "";
    if( request.getSelectedOptions() == null){
        res = "Serialization Failed";
    } else if(request.getSelectedOptions() != null ){
        res = "Serialization Passed";
    }
    return Response.ok(res).build();
    }
