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.

event.getDocument().addPosition(fRememberedPosition);
				} catch (BadLocationException x) {
					fRememberedPosition= null;
				}
			}
		}
		/*
		 * @see org.eclipse.jface.text.IDocumentListener#documentChanged(org.eclipse.jface.text.DocumentEvent)
		 */
		public void documentChanged(DocumentEvent event) {
			if (fRememberedPosition != null) {
				if (!fRememberedPosition.isDeleted()) {
					
					event.getDocument().removePosition(fRememberedPosition);
					fActiveRegion= new Region(fRememberedPosition.getOffset(), fRememberedPosition.getLength());
					fRememberedPosition= null;
					
					ISourceViewer viewer= getSourceViewer();
					if (viewer != null) {
						StyledText widget= viewer.getTextWidget();
						if (widget != null && !widget.isDisposed()) {
							widget.getDisplay().asyncExec(new Runnable() {
								public void run() {
									deactivate();
								}
							});
						}
					}
					
				} else {
