JDK 17 does not support Wayland natively. [Project Wakefield](https://wiki.openjdk.java.net/display/wakefield/OpenJDK+Project+Wakefield+-+Wayland+desktop+support+for+JDK+on+Linux https://wiki.openjdk.java.net/display/wakefield/OpenJDK+Proj...) aims to resolve that. So far, Java GUI applications only support connecting to an XWayland server when on Wayland. This is also stated in the bug you linked.

That’s extremely unfortunate and I’m not sure how I got that impression. I’m quite certain I read this because I spent significant amounts of time trying to get IntelliJ to run on EA versions of JDK… but evidently I’m wrong as it even mentions as such in the link I pasted. :/

  The sad thing is, there are no big technical hurdles to get like 95% of the things to run. What's unclear is how to take screenshots, how to control the mouse pointer and the mouse buttons and how to do input. These are quite far-reaching features that Wayland by design restricts for most applications.

    I wouldn't want an IDE to ever warp my fucking mouse pointer!

  See also this[1] ussue to track the progress. There are problems even with XWayland, e.g. on HiDPI setups. There's a work-in-progress solution [2]. If you are willing to patch the software and build from sources it will help.
