Unable to consume OData v2 JSON formatted response

[GoogleCodeExporter]

What steps will reproduce the problem?
1. I have an OData v2 service
2. I am using OData4j 0.6
3. I do builder.setFormatType(FormatType.JSON);

I am able to consume my service using ATOM XML.

With JSON, I get this following exception for getEntities()

Exception in thread "main" java.lang.RuntimeException:

I am able to consume individual entity : /EntityType('ID') but not collection : 
/EntityType

So, to me this looks like a problem in consuming the OData v2 JSON format

My EntitySet response looks like below:

{
   "d":{
      "results":[
         {
            "__metadata":{
               "uri":"http://localhost:7000/node/odata/CA:00000_NodeA/Alert('Alert_8')",
               "type":"usm-core.Alert"
            },
            "Severity":"Fatal",
            "AlertType":"Risk",
         },
         {
            "__metadata":{
               "uri":"http://localhost:7000/node/odata/CA:00000_NodeA/Alert('Alert_7')",
               "type":"usm-core.Alert"
            },
            "Severity":"Fatal",
            "AlertType":"Risk",
         }
      ]
   }
}

Please close the issue. It was not a problem with OData4J but with my OData 
service.

My service did not respond with "DataServiceVersion" which should have been 
"2.0". Once I put that, it was able to consume JSON Verbose format.
