I would advise against that and in favour of the approach in the Stack Overflow answer. Remember that a virtual thread should normally only ever execute a single task that’s been submitted to an Executor. 

I understand that your intent is good, and that you probably just want to use the convenient “fixed rate” methods of ScheduledExecutorService to run what is *conceptually* a single task, but many of the problems we see with people misusing virtual threads and not getting good results are due to them not internalising this idea that a virtual thread is a single task, so I would suggest not to show this kind of usage to virtual thread beginners.
