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.

break;

		if (marker != null && !marker.equals(fLastMarkerTarget)) {
			try {
				boolean isProblem= marker.isSubtypeOf(IMarker.PROBLEM);
				IWorkbenchPage page= getSite().getPage();
				IViewPart view= page.findView(isProblem ? IPageLayout.ID_PROBLEM_VIEW: IPageLayout.ID_TASK_LIST); 
				if (view != null) {
					Method method= view.getClass().getMethod("setSelection", new Class[] { IStructuredSelection.class, boolean.class}); 
					method.invoke(view, new Object[] {new StructuredSelection(marker), Boolean.TRUE });
				}

			} catch (NoSuchMethodException x) {
			} catch (IllegalAccessException x) {
			} catch (InvocationTargetException x) {
			}
			
		}
