For the record yes, that means if you have #Gnome's ATK-Wrapper installed, #Swing and #AWT both have #accessibility functional on #Linux (assuming you have all the other requirements for an #ATSPI setup to work installed as well, of course).

#Java is an exercise in overcomplicated badly-documented environment magic.

It's not immediately obvious that there is any support for #ATSPI or other #accessibility in #Linux, right?

Well as it turns out, installing https://wiki.gnome.org/Accessibility/JavaAtkWrapper does on most distros magically set that class name property which then gets loaded from a search in various paths.
