getLogoutTab().logOut() in onExit() not working

[Adept]

I have "getLogoutTab().logOut();" in my overriden onExit() method so that the account logs out when I manually stop the script using the GUI. It used to work in previous versions (months ago) but not anymore.
What has changed?
I also tried creating my own logout() method. It works when I place it elsewhere but not in the onExit() method.

this.stop(); might help?
