List All Virtual Threads in a JVM

[Nathan Reynolds]

How do I list all the virtual threads in a JVM?
ThreadMXBean.dumpAllThreads(), ThreadMXBean.getAllThreadIds(),
ThreadGroup.enumerate(), and Thread.getAllStackTraces() do not return
virtual threads.  See my question at
https://stackoverflow.com/questions/79110874/list-the-virtual-threads-in-java
.

I can see how these APIs would not scale for virtual threads.  What are the
thoughts for an API to list all the virtual threads?  For an in-process
API, would an API that returns Stream<Thread> scale?  I am not sure how an
MXBean API can stream Threads to make it scale.
