Using Exclipse running in 14.04: with the default Unity behaviour, the application menu behaves more or less correctly. With the setting changed to 'show menu in window's title bar' the same application menubar behaves incorrectly: some top level menus drop down, some do not. In some drop downs, the dropped list is incomplete and/or incorrectly enabled. It would appear to me that this ought not to be an application issue, but with Unity, Java, Swing and Eclipse all involved, I cannot be definitive: it may be a Unity bug.
