This would mean each Gtk-based DE will require a patch to OpenJDK, which is
unsustainable.

There is no such thing as GTK desktop


Wikipedia has its own category:
https://en.wikipedia.org/wiki/Category:Desktop_environments_based_on_GTK

In regards to Gtk2 versus Gtk3 binding, those issues haven't changed as
results of this missing variable.  To request an environmental variable
which exposes this is a reasonable request.  I'm not sure I understand the
reluctance to provide such information.
