Most of the desktop related changes are related to Assistive Technologies
I don't think we currently provide a 32-bit windowsaccessbridge.dll in the 64 bit JDK, but I'd like to be sure I am not forgetting something.
The point being windowsaccessbridge.dll is not loaded by the JDK, but by an AT, so traditionally we provided both 32 and 64 bit versions because we don't control that AT.

So I would like Alex Zuev to review these changes. For whatever reason his git hub handle doesn't seem to be found. I think it is something like @azuev-java
