Bug 20533 Unexpected popup closing eclipse with unsaved changes
Build 20020617 Win2k I'm not sure if this is core, but... - In the resource perspective, create a new simple project - Create a .txt file in this project - Type something in it (to flag it as modified) - close eclipse - it will ask you if you want to save it before exiting, save it Now you should see another dialog pop up saying: "The file has been changed on the file system. Do you want to load the changes? (Yes/No).

					return null;
					
				int length= problem.getSourceEnd() - problem.getSourceStart() + 1;
				if (length < 0)
					return null;
					
				return new Position(start, length);
