Are you talking about JAVA Applications or JAVA Applets.  Java applications
have much more access to the computer and peripherals than JAVA Applets -
that must run in the security sandbox.

Java is an independent enviroment from OS. It didn't ereditate OS
accessibility characteristics like:
- text size and colour
- colour theme (eg. High contrast)
there are also some "plug-in" like Java Accessibility Bridge that should
guarantee the use of assistive technologies.

    Imagine a Java applet with a fair sized text entry area or two.
    
     
    
    GV: yes that would be the way to look at this.  
    
     
    
    My question is this:  Could a Java applet could ignore (probably not
    deliberately, but by accident of design) StickyKeys (or FilterKeys or
    SerialKeys or SoundSentry) within the domain of the Java applet?  Or is
the
    VM wholly dependant on the OS to pass text?  Is a Java applet limited to
    "key up" event handlers, or can it watch for "key down" (and thus
possibly
    prevent capitalization when StickyKeys is running on the OS)?
    
     
    
    GV: my understanding is that it is completely dependent on the  OS to
pass
    text.  that is part of the 'security sandbox'.  StickyKeys etc are
    implemented very low so that all apps pick them up.  So unless the
    application was looking at timing of keyups and keydowns to specifically
    identify modifier keys that were consistently pressed a give amount of
time
    before other keys and therefore must be done by machine or something -
    (which means the company is using heuristics specifically designed to
bypass
    access features) I don't think it would be a problem.
    
     
    
     
    
    I wasn't thinking about Alt-Tab not working when I raised this question.
I
    am not worried so much about assistive technology being turned off.  I
    remain still a little anxious about the potential for accessibility
features
    of the operating system to be ignored (which is what 1194.21(b) is
about)
    within the virtual machine.  Your contact at Sun may have considered
this
    aspect as well, but the answer you quote back doesn't address this
concern.
