Description of problem:
When querying tasks which do not have an actual owner by using
- the /rest/task/query,
- or TaskService.getTasksByVariousFields(...) method (which the REST operation depends on)
these methods will not find the tasks in question.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Create a task that does not have an actual owner
2. Query the tasks using a valid criteria (process instance id, for example)
3. Check the results
No tasks are returned.
The correct tasks are returned.
This bug means that there are cases in which the user will not be able find the task created by a process instance.
My apologies: somehow, 2 different tests both failed repeatedly during the same hour, after which both started passing again.
This bug somehow magically disappeared after an hour of looking into it.
