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.

sourceViewer.configure(getSourceViewerConfiguration());
		getSourceViewerDecorationSupport(sourceViewer).install(getPreferenceStore());

			enableBrowserLikeLinks();
		
		internalDoSetInput(input);
	}
	
	private void internalDoSetInput(IEditorInput input) throws CoreException {
		super.doSetInput(input);
		
		if (getSourceViewer() instanceof JavaSourceViewer) {
			JavaSourceViewer viewer= (JavaSourceViewer)getSourceViewer();
			if (viewer.getReconciler() == null) {
				IReconciler reconciler= getSourceViewerConfiguration().getReconciler(viewer);
				if (reconciler != null) {
					reconciler.install(viewer);
					viewer.setReconciler(reconciler);
				}
			}
		}
		
		if (fEncodingSupport != null)
			fEncodingSupport.reset();
		
		setOutlinePageInput(fOutlinePage, input);
				
		if (fProjectionModelUpdater != null)
			fProjectionModelUpdater.initialize();
