Bug 8595 'Open super implementation' should be disabled
In the Outline view, there seems to be a new menu item 'Open super implementation', and a corresponding decoration on methods to indicate thet they have a super implementation. The UI already knows if the method has a super implementation, so it should disable the menu item when there is no super implementation to open to. Currently it just does nothing if you select a method with no super implementation. (Tested against 20020125 build)
