JAWS does not read the JPassword.setEchoChar() character correctly

I have set JPassword.setEchoChar('@') and expected that JAWS will read '@' char but instead JAWS read it as '*'(star) character.

Step to reproduce
-------------------------
1) Enable accessibility using <jdk-path>/bin/jabswitch -enable
2) Start JAWS
3) Run the attached test. Once the Frame is visible with JPassword.
4) Type any character(s) into JPassword and you should see '@' character only. If JAWS reads '@' as * then bug is reproduced

This works as expected on MacOS.
I have attached the Screen Recording of the same.
