If you search for "/usr/include/gtk-2.0/gtk/gtktypeutils.h:236:64: error: ‘GTypeDebugFlags’ is deprecated [-Werror=deprecated-declarations]" or "Gtypedebugflags is deprecated" in this pastebin: https://paste.ubuntu.com/p/9cqrV52Rtz/ (or in the attached txt file) you'll see that it also fails having to do with gradle, presumably because of the GTK stuff failing. Also when I do emerge -auDN @world, dev-java/javax-inject-1-r3 also fails to upgrade. I'm trying to get full functionality out of Java-based app FileBot. Without openjfx installed FileBot functions, but as it is a renaming tool it will not actually append and write the renamed file unless some sort of JavaFX class is installed.
