Java/Swing: Desktop.open() causes GTK-ERROR

I am currently developing a Swing Desktop application. This application is also using a tray icon which is handled by SystemTray of dorkbox.

Now I need to open a file with the default application. To achieve this I am using the Desktop.open() method of AWT like this.

if (Desktop.isDesktopSupported()) {
    System.out.println("Get desktop.");
    Desktop desktop = Desktop.getDesktop();
    System.out.println("Got desktop.");
    desktop.open(file);
}

But now here comes the problem: On some devices (which apparently have GTK2 and GTK3 installed this few lines make application crash - the program crashes while executing the Desktop.isDesktopSupported() line with a gtk-error ** gtk+ 2.x symbols detected. using gtk+ 2.x and gtk+ 3 is not supported.

To be honest, I have no clue, what is going wrong here - but if only GTK3 is installed the application runs like a charm. The SystemTray seems to be using GTK3 as well because I did not explicitly set it up to use GTK2. So, what's causing this mix of GTK2 and 3? Is there a way to force the Desktop class to use the right version of GTK (the same, as being used by the rest of the application)?

It won't resolve your current problem but there is another way to open file with the default application.

On Windows:

Runtime.getRuntime().exec("C:\SomeFolder\Somefile.txt");

On Mac and Linux:

Runtime.getRuntime().exec("xdg-open /folder/file.txt");

Hope it will help you, if you won't resolve your current problem.
