Getting exception on IQueryResult

Hello,

I am trying to create a java program to get run a shared query. I am able to get the IQueryDescriptor object pertaining to the query selected by user. But when I am trying to get the result am getting exception (org.eclipse.core.runtime.AssertionFailedException: assertion failed).

Version being used : 6.0.1

PFB the function to get the result set

public static void getResultSet(ITeamRepository repository,IQueryDescriptor query)
    {
        try
        {
            IWorkItemClient workItemClient = (IWorkItemClient) repository.getClientLibrary(IWorkItemClient.class);
            IQueryClient queryClient = workItemClient.getQueryClient();
            ItemProfile loadProfile = IQueryDescriptor.FULL_PROFILE;
            IQueryResult<IResolvedResult<IWorkItem>> resolvedResults = queryClient.getResolvedQueryResults(query, loadProfile);
            long processed = 0;
            System.out.println("Size : " + resolvedResults.getResultSize(null).getTotal());
            while(resolvedResults.hasNext(null))
            {
                IResolvedResult<IWorkItem> result = resolvedResults.next(null);
                IWorkItem item = result.getItem();
                System.out.println(item.getItemId());
                processed++;
            }
            System.out.println("Processed : " + processed);
        }
        catch(Exception e)
        {
            System.out.println("Exception : " + e.getMessage());
            e.printStackTrace();
        }
    }

Could someone please tell me how to remove the exception.

Thanks in advance !!!
