OpenJDK Java's Native Wayland Support Progressing

Written by Michael Larabel in Wayland on 24 September 2022 at 02:21 PM EDT. 50 Comments
OpenJDK/Java has been making progress on implementing native "pure" Wayland toolkit integration not dependent upon X.Org/X11 or XWayland for rendering of Java GUI applications.

Developer Alexey Ushakov updated the OpenJDK Wiki this week to outline the latest progress being made on getting Wayland support for OpenJDK on Linux to complement the mature X11 support.

This new toolkit support continues to be implemented from scratch and currently development is being done via Java's Wakefield repository with the "pure_wl_toolkit" branch. Much of the testing so far appears to have been done with Wayland's Weston reference compositor and using Ubuntu 21.10.
