Can this be made to work out of the box? jtreg strips env variables down to a very few. so providing following options should solve the issue: `jtreg -ea -e:DBUS_SESSION_BUS_ADDRESS=$DBUS_SESSION_BUS_ADDRESS -e:WAYLAND_DISPLAY=$WAYLAND_DISPLAY ...` This is already addressed in jtreg 7.3 by [openjdk/jtreg/pull/152](https://github.com/openjdk/jtreg/pull/152) > 2.
