MenuBar: IOOB exception on requestFocus on empty bar

    Details

      Description

      To reproduce, compile and run the example below and see the stacktrace.

      This turned up during binch testing for JDK-8244112 for all controls (failed in sanity test of setup state) Will exclude MenuBar with a pointer to this issue.


      The example:

      /**
       * Empty MenuBar throws IIOOB on requestFocus.
       */
      public class MenuBarEmptyRequestFocus extends Application {

          private MenuBar bar;
          private Parent createContent() {
              bar = new MenuBar();
              VBox content = new VBox(bar);
              return content;
          }

          @Override
          public void start(Stage stage) throws Exception {
              stage.setScene(new Scene(createContent()));
              stage.show();
              bar.requestFocus();
          }

          public static void main(String[] args) {
              launch(args);
          }

      }
