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.
