I got the exception below when trying to invoke activateTask() from a non-UI thread:

Task activation has been considered a UI action, because it has always been intended to correspond to a user's intention to activate a task.  So I wonder if we make this constraint explicit in the API, or if we should make actions like AbstractAutoFocusViewAction safe to calls made outside of the UI thread.
