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.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/javaeditor/JavaEditor.java
/**
		 * Creates a new select next sub-word action.
		 */
		public SelectNextSubWordAction() {
			super(ST.SELECT_WORD_NEXT);
		}
		/*
		 * @see org.eclipse.jdt.internal.ui.javaeditor.JavaEditor.NextSubWordAction#setCaretPosition(int)
		 */
		protected void setCaretPosition(final int position) {
			final ISourceViewer viewer= getSourceViewer();
			
			final StyledText text= viewer.getTextWidget();
			if (text != null && !text.isDisposed()) {
				
				final Point selection= text.getSelection();
				final int caret= text.getCaretOffset();
				final int offset= modelOffset2WidgetOffset(viewer, position);
				
				if (caret == selection.x)
					text.setSelectionRange(selection.y, offset - selection.y);
				else
					text.setSelectionRange(selection.x, offset - selection.x);
			}
		}
