I'm not saying that virtual threads aren't a good thing (other runtimes than the JVM have had green threads for a very long time now), but that it doesn't seem like such a paradigm shift. It's still threads (with all the benefits and drawbacks), it's just now that they have less overhead.

Presumably I could just keep an existing server written in Spring MVC or a similar technology and just wait for the underlying container to support virtual threads to get the same benefits. I believe Jetty already does support them. So why would I need a new framework?

It removes the need to write async code in many cases. It is a more straightforward and efficient way to accomplish what we have already been doing for years on the JVM.

You don't need to switch frameworks
