Bug 6758 Class name corrupted by creating member class using wizard
Build 20011206 - opened org.eclipse.ui.actions.DeleteResourceAction - using new class wizard, created member class named DeleteProjectDialog as a subclass of MessageDialog (in org.eclipse.jface.dialogs) - the result was: ... public class DeleteRes ourceAction extends SelectionListenerAction { public class DeleteProjectDialog extends MessageDialog { } ... Note the extra tab in DeleteResourceAction, and the strange formatting for the new class.
