Bug 148993 [Workbench] Wrong Javadoc for IDE.getEditorDescriptor
3.2 and latest 3.3 build The Javadoc of IDE.getEditorDescriptor(...) does not mention that as a very last resort it tries to find the editor descriptor for the default text editor i.e. IDEWorkbenchPlugin.DEFAULT_TEXT_EDITOR_ID (org.eclipse.ui.DefaultTextEditor)

	 * @return The editor input associated with the given file store
	 * @since 3.3
