During the presentation at Devoxx 2022 Belgium, there was a question about Virtual Threads whereas the answer would be 

---------
spock
worf
---------

After some tests I did, this is actually not correct. The answer can also be 

---------
worf
spock
---------

Because you can never guarantee in which order a thread will be executed in Java.
