Hi,

I have found a solution. Apparently I must specify a human task client (session) id to the constructor of the AsyncHronetQTaskClient class. It works fine with following code:
 public static void main(String args[])
 {
  String user="krisv";
  String language="en-UK";
  List<Status> status = Arrays.asList(new Status[] { Status.Reserved });
  
  String clientSessionID = UUID.randomUUID().toString();
  System.out.println("*** Connecting to human task service with HornetQ protocol, using client session ID: " + clientSessionID);
  SyncTaskServiceWrapper tk = new SyncTaskServiceWrapper(new AsyncHornetQTaskClient(clientSessionID));
  tk.connect("127.0.0.1", 5445);
  
  System.out.println("*** Getting " + status + " tasks for " + user + " with language " + language);
  List<TaskSummary> tasks = tk.getTasksAssignedAsPotentialOwnerByStatus(user, status, language);
  
  System.out.println("*** Got " + tasks.size() + " tasks");
  
  System.out.println("*** Closing connection");
  try {
   tk.disconnect();
  } catch (Exception e) {
   System.out.println("*** Error during disconnect: " + e.getMessage());
  }
  System.exit(0);
 }

Thanks and kind regards,
Alex

PS: I found the solution thanks to the jbpm-examples module, in which the human task example also specifies a (hard-coded) client-session-id to the constructor.
