Then its AccessibleContext is fetched and that AccessibleContext's AccessibleAction is returned. Note that if an AccessibleAction is not found using this process then this object with its implementation of the AccessibleAction interface is returned.
      Returns:
      AccessibleAction if supported by object; else return null
