As announced , we do not intend to release Debian 10 "Buster" with
the old libgnome (and related) libraries. As part of this process, I
am now raising the severity of this bug.
libswt-gnome-gtk3-jni has only 2 rdepends in Debian: eclipse-rcp and
zekr. eclipse-rcp only recommends libswt-gnom3-gtk3-jni and zekr was
removed from Testing last year because it depends on the old
webkitgtk. So maybe this bug can be fixed by dropping the
libswt-gnome-gtk-4-jni still has no rdepends in Debian.
