What happens when a virtual thread encounters a blocking I/O operation?

Answer
The JVM releases the OS thread and parks the virtual thread.
When a virtual thread hits a blocking I/O operation, the JVM efficiently parks it, freeing up the OS thread for other tasks. This prevents the waste of OS resources and allows the system to handle more concurrent operations. For instance, when a virtual thread in an e-commerce application waits for a database response, the JVM can allocate the OS thread to another virtual thread that needs immediate CPU time.
