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.

try {
				type= TextUtilities.getContentType(document, IJavaPartitions.JAVA_PARTITIONING, offset, true);
			} catch (BadLocationException exception) {
				
			}
			
			int index= super.getLineStartPosition(document, line, length, offset);
			if (type.equals(IJavaPartitions.JAVA_DOC) || type.equals(IJavaPartitions.JAVA_MULTI_LINE_COMMENT)) {
				if (index < length - 1 && line.charAt(index) == '*' && line.charAt(index + 1) != '/') {
					do {
						++index;
					} while (index < length && Character.isWhitespace(line.charAt(index)));
				}
			} else {
				if (index < length - 1 && line.charAt(index) == '/' && line.charAt(index + 1) == '/') {
					index++;
					do {
						++index;
					} while (index < length && Character.isWhitespace(line.charAt(index)));
				}
			}
			return index;
		}
