Bug 128825 [navigation] Long pause and exceptions pressing Ctrl+O
Build: 3.2 M5 While waiting for a long CVS checkout, I was browsing through some Java code. I hit Ctrl+O to open the outline, typed some characters ("get"), and then hit Ctrl+O again to show inherited members. There was a pause, and then the outline view went blank. After that, toggling Ctrl+O or changing the filter text in the outline had no effect - the view was just blank. After closing the outline popup completely and reopening, it was behaving as expected. While doing this, a large number of OperationCanceledExceptions appeared in my log file (log attached).

		viewMenu.add(fLexicalSortingAction);
		viewMenu.add(fSortByDefiningTypeAction);

			} catch (JavaModelException e) {
				return null;

			fTypeHierarchies.put(type, th);
		}
		return th;
