Java: Other

The Able to Include Accessibility Layer for Java is available under the Apache License, Version 2.0 and enables applications to work with the Able to Include context-aware accessibility layer, which was developed to improve the day-to-day life of people with IDD by understanding their surroundings and helping them to interact with the information society. (GitHub repositories last updated in 2017; accessed on 16.05.2022.)
~~See also the Accessibility Layer API documentation.~~ These tools were developed by the Able to Include project, which ran from March 2014 till February 2017.

GTK+

GTK+ is a multi-platform toolkit for creating graphical user interfaces. The GNOME developer documentation explains the relationship between GTK+ and ATK as follows: GAIL (GNOME Accessibility Implementation Library) is an implementation of the accessibility interfaces defined by ATK. GTK is a toolkit which is already mapped to ATK by the GAIL module. Note that this applies only to GNOME. According to this message to the GTK-devel mailing list (April 2012) and GNOME bug 303304, GTK+ does not support MSAA or any other accessibility API that works on Windows (IAccessible2, Windows UI Automation).

  This blog post is not primarily about IAccessible2 but about other aspects of mering Lotus Symphony code into OpenOffice. A section near the bottom states, IAccesible2 is an interface used by "assistive technologies" (screen readers, etc.) to help persons with disabilities use desktop applications. We're bringing the IAccesible2 support from Symphony into OpenOffice.
