Make JPopUp (Context menus) Scrollable

If you are working on a not big laptop sometimes the amount of features inside of the context menu, doesn't fit into the screen or is overloaded. (Hardware is still powerful but other resolution and other window size: http://www.browsercheck.me/de/report/gn4y8epgkxwggkk/)

So for this, I prefer to change the behaviour of the JPopupMenu that it should be scroll inside of it. See here a suggestion: http://trelford.com/blog/image.axd?picture=ContextMenu_thumb.png

VS Code also implemented it: https://code.visualstudio.com/updates/v1_30#_scrolling-menus

So they are implemented it not only for menus, as the description says. And I think for NetBeans it doesn't matter whether it is a context menu, when you right click or a menubar entry. Only guessing, that all of them are JPopupMenus. If not, please let me know, then I will create a new ticket for the menus too.
