The failure was observed on Ubuntu 21.04. It was not observed on Ubuntu 18.04. The test passed successfully on Windows and macOS.

It is not a regression since similar failure was observed on 11.0.2+9

Probabaly it imay be a Wayland specific failure.
Comments
Will be fixed as part of JDK-8280988

It is known Wayland limitation for Java. There are several tests which are trying to get window focuses by clicking on its window title. Window's decorations are made on Wayland side, they are not reachable by XTest emulation code(which is purely X11). One of possible workarounds is to press somewhere inside of the window.
