OpenJDK/Java has made progress in enabling native “pure” Wayland toolkit integration that does not rely on X.Org/X11 or XWayland to render Java GUI applications.

Developer Alexey Ushakov updated the OpenJDK Wiki this week with an overview of the latest developments in OpenJDK’s Wayland support on Linux, which is a further refinement of the mature X11 support.

This new toolkit support continues to be implemented from scratch and is currently being developed through the Wakefield repository for Java and the “pure_wl_toolkit” branch. So far, most of the testing seems to have been done with Ubuntu 21.10 using Wayland’s Weston reference synth.

Here are some of the main tasks of the toolkit:

▲ OpenJDK developers show their Wayland “WLToolkit” using Java progress

▲ Keyboard and mouse input have been implemented

See the OpenJDK Wiki page and the JDK-8281970 bug tracker for details.
