Is it possible to force jQuery.jScrollPane to always show a vertical scroll-bar?
e.g. hidden setting, API function?
Preferably without touching the content pane, its height etc.
Unfortunately this isn't currently possible with jScrollPane. There is an open feature request for it though:

As a workaround for now you could place an element with a min-height directly inside your scrollpane to force the scrollbar like in this example:

Hope it helps!
another method which I've confirmed will work is to add a new parameter "alwaysShowScroll:true" and make two changes in jquery.jscrollpane.js:
~line 176, change if (!(isScrollableH || isScrollableV)) {
to if (!(isScrollableH || isScrollableV || settings.alwaysShowScroll)) {
~line 241, change if (isScrollableV) {
to if (isScrollableV || settings.alwaysShowScroll) {
