The example project fails with (UnsupportedOperationException) about cljfx HOT 6 CLOSED

Can you get any of the other examples to work in a REPL? There are a bunch of code snippets in the samples directory.

Hi! Looks like an internal error in JavaFX:

{:type java.lang.UnsupportedOperationException
 :message "Internal Error"
 :at [com.sun.glass.ui.gtk.GtkApplication lambda$new$6 "GtkApplication.java" 189]}

from cljfx.

Line numbers are a bit off, but here is the code that might throw:

        @SuppressWarnings("removal")
        boolean gtkVersionVerbose =
                AccessController.doPrivileged((PrivilegedAction<Boolean>) () -> {
            return Boolean.getBoolean("jdk.gtk.verbose");
        });
        if (PrismSettings.allowHiDPIScaling) {
            @SuppressWarnings("removal")
            float tmp = AccessController.doPrivileged((PrivilegedAction<Float>) () ->
                    getFloat("glass.gtk.uiScale", -1.0f, "Forcing UI scaling factor: "));
            overrideUIScale = tmp;
        } else {
            overrideUIScale = -1.0f;
        }

from cljfx.

given that exception is coming from lambda, it might be either from Boolean.getBoolean("jdk.gtk.verbose") or from getFloat("glass.gtk.uiScale", -1.0f, "Forcing UI scaling factor: "). Can you check these system properties? What's the result of (System/getProperty "jdk.gtk.verbose") and (System/getProperty "glass.gtk.uiScale")?

Hi vlaaad, both properties are nil. But, I've found something strange. An example works, if I use another version of libGL.so. with mesa-21.2.5 it works, with my system-wide mesa-21.3.2 fails as I described above. Any idea what is going on?

please ignore the message above, I'v confused myself. The problem was in my installation, I didn't have libgtk-3.so on my host, after add the proper package (gtk+ for my guix installation), the example started to work.
