I've find the solution of this probelm.

In order to solve this problem, we need to use this version of task complete method:


    BlockingTaskOperationResponseHandler responseHandler = new BlockingTaskOperationResponseHandler();
 
    Map<String, Object> taskVariables = new HashMap<String, Object>();
    taskVariables.put(new String("o_validationResult"),Boolean.valueOf(true));
 
    ContentData contentData = null;
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    ObjectOutputStream out;
    try {
      out = new ObjectOutputStream(bos);
      out.writeObject(taskVariables);
      out.close();
      contentData = new ContentData();
      contentData.setContent(bos.toByteArray());
      contentData.setAccessType(AccessType.Inline);
    } catch (IOException ioe) {
                 ioe.printStackTrace();
    }
 
    client.complete(aTaskId, aOwnerId, contentData, responseHandler);
 


With this code the task completion with a map of variables must done successfully.
