[SceneBuilder,MenuBar] NullPointerException in Cascading menu when running SceneBuilder

    XMLWordPrintable

    Details

      Description

      While testing SceneBuilder on Linux, I twice (with two different runs) got the following exception. No steps to reproduce this since it is intermittent.
