Bug 66234 [projection] Revert file sometimes does not display the imports
I was able to recreate the scenario, I have a Java file in a Java project as /* * Created on Jun 8, 2004 * * TODO To change the template for this generated file go to * Window - Preferences - Java - Code Style - Code Templates */ package com; import java.net.URL; import java.util.Date; /** * @author admin * * TODO To change the template for this generated type comment go to * Window - Preferences - Java - Code Style - Code Templates */ public class Test { Date xyz; URL abc; } I open it in the editor, delete the keyword 'package' so that that line only says com. Now I right click on file and select 'Revert File'. Notice that the imports list disappears. This is in M9.

int offset= anchor;
				char c;
	
				while (offset >= 0) {
					c= document.getChar(offset);
					if (!Character.isJavaIdentifierPart(c))
						break;
					--offset;
				}
	
				int start= offset;
	
				offset= anchor;
				int length= document.getLength();
	
				while (offset < length) {
					c= document.getChar(offset);
					if (!Character.isJavaIdentifierPart(c))
						break;
					++offset;
				}
				
				int end= offset;
				
				if (start == end)
					return new Region(start, 0);
				else
					return new Region(start + 1, end - start - 1);
