(1) No, IIRC Apple does not use the Java Accessibility API and Java Access Bridge for its native 
Aqua/Cocoa NSAccessibility framework as used in VoiceOver. And OOo/LibO accessibility libraries 
make use of roles from NSAccessiblity framework to support OS X builds.

But for development/implementation of non-Aqua/Cocoa Java accessible applications under OS X, a JRE 
and Java Access Bridge is required on OS X.

So, with Oracle now building the JRE used by OS X, it could conceivably be having an impact on the 
Apple Accessibility APIs.

(2) The Java Access Bridge is capable of supporting all assistive technologies that are implemented 
in Java, but most defined roles came from the earlier Microsoft work on MSAA and IAccessible.  The 
a11y accessibility working group has moved beyond that with IAccessible2, ATK/GAIL and AT-SPI 
efforts. And of course Microsoft is doing its own thing for Windows, replacing the MSAA/IAccessible 
with UI Automation.  Both the Accessibility wiki and the Java wiki documentation can use more work.

Hi :)
There is a guide to help fix Accessibility issues on Windows by fixing the "Java Accessibility 

Does Mac also depend on Java for these accessibility tools?  I've got a feeling that the JAB is 
just for screen-readers?  Also the page doesn't help 100% of the time but i think it's not far off. 
 Suggestions or expanding it to other platforms would be great :) Regards from Tom :)

Alex, thank you for this info - it finally tells me where to look.  In Mac OS X.6.8, Accessibility 
Tools is called Universal Access, and yes, I do have that turned on, for two reasons: to be able to 
magnify an area of the screen on occasion, and to run Zooom 2, which provides focus-follows-mouse. 
Both of these, and especially the latter, are very useful, so I'll wait for LO version
3.6.3 to see if that solves the crashing problem.

Thanks for pointing me out of limbo.

- Dushan
