Comment 1 Mik Kersten CLA 2007-11-26 23:40:04 EST 
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.
