How to get the content of a change set, which is linked to a work item, exactly how it is visible in the RTC web client using Jazz SDK ver. 5.0.2.05

As I recall, when a change set is linked to a work item, if there is a "current" workspace at the time of linking, a reference to that workspace is added as a property on that link.   Then if a pathname for a member of that change set is requested, some of the clients will check to see if there is a link from that change set to a work item, and if so, they will check to see if that link has that workspace property, and if it does, use that workspace to determine a pathname for that file.

My Analysis showing why Team Advisor pops up with a PermissionDeniedException regardless I catch the exception:

1) my code tries to get a workspace connection (context) in order to get the full path of all changed files in a changeset: wsManager.getWorkspaceConnection(...)
2) com.ibm.team.scm.client.internal.WorkspaceManager.getWorkspaceConnection(...) calls getServerConfigurationService().refreshWorkspaces(...)
3)  getServerConfigurationService().refreshWorkspaces(...) calls com.ibm.team.scm.client.internal.ScmServiceInterfaceProxy.invoke(...)
4) ScmServiceInterfaceProxy.invoke(...) calls ScmServiceInterfaceProxy.invokeCancelableService(...);
4.1. ScmServiceInterfaceProxy.invokeCancelableService(...) throws a PermissionDeniedException
4.2. ScmServiceInterfaceProxy.invoke(...) catches the exception
4.2.1. shows Team Advisor view using the notifyProcess(...) (see Step 4 in the code below)
4.2.2. and finally passes the exception to the caller IWorkspaceConnection getWorkspaceConnection(...) (see Step 5 in the code below)
5) IWorkspaceConnection getWorkspaceConnection(...) passes the exception to my code which is processed as well.  (see Step 7 in the code below)
 


My plug-in code:
    ....
    try {
        if(wsHandle != null) {

           // Step 1:  IWorkspaceConnection getWorkspaceConnection(...) is executed

            IWorkspaceConnection wsConn =
                wsManager.getWorkspaceConnection(
                     (IWorkspaceHandle) wsHandle,
                    child.newChild(25));
             ...
        }//if
        ...
    }//try
    catch(Throwable e) {
        // Step 7: The exception PermissionDeniedException is processed here as well
        System.out.println("Throwable: " + e.getMessage());
        return result;
    }

            IWorkspaceHandle workspace,
