The attachment to JDK-8028241 (Test.java) has a menu item with Ctrl-Alt-Shift-Delete.
JAWS does not read it at all.
I tested jdk 8u40b01 and 8u40b08 x64 on Win 7 x64.

8u25b15 has another behaviour. on 8u25 JAWS read Ctrl-Alt-Shift-Delete incorrectly as "D shift+D" for some reason.
Not a regression because this functionality has never worked properly for jdk 8.

1)copy *-64.dll from jre/lib of tested x64 jdk to Windows folder
2)run JAWS x64
3) run test.jar from attachment to main bug JDK-8028241.
4) press Alt-F
5) press down arrow buttons and check how JAWS spells accelerators.
6) Notice that accelerator for Del item is not spelled by JAWS
