headless Swing UI testing

Project mention: Swingland: Recreating Java Swing for Wayland | dev.to | 2023-05-12

It turns out Java GUI technology has been somewhat abandoned by Oracle, in particular when running Swing (or JavaFX) applications on Wayland, Java relies on the XWayland adpater to bodge X11 API calls back to Wayland proper. This is not great (read: doesn't work out of the box), so I wondered if someone had implemented a native Wayland backend for Swing - and they have, multiple times - super, but wait.. Oracle have not merged either project into mainline Openjdk, and indeed the only way to make either of them work is by hideous bodging, which also puts paid to any thoughts of writing my own backend, as the hacks required to load it at run time (read: in every application) are not sustainable. Grrr! So what to do?
