So why can't I just use an OS regular thread to use a non-blocking API? What is the advantage of a virtual thread in that case? You are saying that it's painful? How exactly? If you use an Executor that's setup with a proper Thread Pool it's mostly painless? I mean, virtural threads are nicer but I see that as almost a syntax issue. A bit cleaner. I guess I'm asking what you mean by 'painful to use?'.
