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
final ISourceReference reference= (ISourceReference)element;
									final ISourceRange range= reference.getSourceRange();
									if (range != null) {
										viewer.setSelectedRange(range.getOffset(), range.getLength());
										viewer.doOperation(ISourceViewer.FORMAT);
									}
								}
							}
						} catch (JavaModelException exception) {
							
						}
					} else {
						viewer.setSelectedRange(selection.x, 1);
						viewer.doOperation(ISourceViewer.FORMAT);
					}
				} catch (BadLocationException exception) {
					
				} finally {
					viewer.setRedraw(true);
					viewer.restoreSelection();
				}
			}
		}
	}
