Is there a way for a Java Swing desktop application that runs in Gnome (3.14) on Linux (Debian) to make Gnome use the dark-themed (Adwaita) version of the window decoration?
I am using a custom dark Swing look-and-feel, and the only thing that is really annoying is that the title bar (native Gnome) is very bright. I already have used the Tweak tool to use Adwaita system-wide, but this doesn't kick in for applications that do not explicitly support dark-theme (e.g. Iceweasel, Icedove, Gimp, Libre Office, ...)
Here's a screenshot that illustrates the problem:
