Description Sumit 2011-03-08 00:03:26 EST

Build Identifier: jetty-hightide-8.0.0.M2

I am trying access my Java POJO classes with BlazeDs deployed in Jetty server. For small requests things are working fine. But for list(ArrayList) of java object as response drill down to a hang in server. For detail see steps to reproduce. 

Reproducible: Always

Steps to Reproduce:
Steps to reproduce:

Just copying the code I used to simulate problem

*part of MXML*

        <mx:RemoteObject id="srv_RO" destination="product_RO"/>
        <mx:DataGrid dataProvider="{srv_RO.getProducts.lastResult}" width="100%" height="100%" x="70" />
<mx:Button label="Get" click="srv_RO.getProducts()" />

====================================
*sumit/SumitProduct.java*

package sumit;

public class SumitProduct {
    private String name;
    private int price;

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getPrice() {
        return price;
    }
    public void setPrice(int price) {
        this.price = price;
    }
}

==============================
*sumit/SumitProductService.java*

package sumit;

import java.util.ArrayList;
import java.util.List;
import java.util.Random;
//import flex.messaging.io.ArrayCollection;

public class SumitProductService {
    private static final String[] MASTER_LIST = {"C", "FNM", "FRE", "F", "GOOG",
"AIG", "CSCO", "MSFT", "AAPL", "YHOO", "BSX", "PORT","F", "TNT", "ESP", "RET", "V
BN", "EES"};

    public SumitProductService(){}

    public List<SumitProduct> getProducts(){
        List<SumitProduct> list = new ArrayList<SumitProduct>();
        Random r = new Random();
        for (String s:MASTER_LIST){
            SumitProduct sq = new SumitProduct();
            sq.setName(s);
            sq.setPrice(r.nextInt(50));
            list.add(sq);
        }
        return list;
    }
}

 
 Actual Results:
 Hang ... no result
 Error is :- [BlazeDS]09:19:26.225 [ERROR] class sun.reflect.GeneratedMethodAccessor7 cannot access its superclass sun.reflect.MethodAccessorImpl
 
 Expected Results:
 records set
 
 
 Workaround (if any):
 NO
