JEP 353 put in the foundation to enable this and JEP 425 makes use
of it, see the Networking section [1] in the JEP and specifically:<br>
<br>
"To allow for interruption and cancellation, the blocking I/O
methods defined by java.net.Socket, ServerSocket, and DatagramSocket
are now specified to be interruptible when invoked in a virtual
thread"<br>
<br>
So in the HTTP/1.1 scenario here, where a virtual thread is blocked
on an idle persistent connection, the shutdownNow will cause the
virtual thread to wakeup and close the connection.<br>
