jBPM User Task snapshot

Description of problem:
As attached usertask.png show, if we define Content, then Content value will replace all other perams(Name, Actor(s), Groups(s), etc), we can use the following code test:
                List<TaskSummary> list = localTaskService.getTasksAssignedAsPotentialOwner("john", "en-UK");
                TaskSummary task = list.get(0);
                Task taskDef=localTaskService.getTask(task.getId());
		Content content = localTaskService.getContent(taskDef.getTaskData().getDocumentContentId());
		ByteArrayInputStream bais = new ByteArrayInputStream(content.getContent());
		ObjectInputStream ois =null;
		HashMap taskinfo = null;
		try {
			ois = new ObjectInputStream(bais);
			Object obj = ois.readObject(); 
			System.out.println("Extract via API: " + obj);
		} catch (ClassNotFoundException e) {
		} catch (IOException e) {
If Content has been defined, above code will output only Content value as a String;
If no Content defined, all perams(Name, Actor(s), Groups(s), etc) will output as a HashMap.

This not a bug verify by JBoss SEG, but no document refer to this, I do think this should be included in the API (java) documents or user guide.

One of Develop said, this also shuld not be bug, as below:

"after a salaboy commit some time ago, now, the input of the task will be get from the “content” variable. If you want to send many separate variables, you can omit (send it blank) the content variable, and add other variables. If the human task work item handler  does not find anything in content variable, it will send a map with all the task variables as input."

Expected results:
This be state in  API (java) documents or user guide
