In addition, this implementation detail might help in gaining some insight: "The synchronous networking Java APIs, when run in a virtual thread, switch the underlying native socket into non-blocking mode. When an I/O operation invoked from Java code does not complete immediately (the native socket returns EAGAIN - “not ready” / “would block”), the underlying native socket is registered with a JVM-wide event notification mechanism (a Poller), and the virtual thread is parked. When the underlying I/O operation is ready (an event arrives at the Poller), the virtual thread is unparked and the underlying socket operation is retried." https://inside.java/2021/05/10/networking-io-with-virtual-th... |
