Unfortunately, your premise is incorrect. Daemon threads do not terminate when the parent thread terminates.

Daemon threads do not prevent the JVM from exiting, meaning that if only daemon threads are running the JVM may exit. If even a single user thread is running, the JVM will continue to run, along with the Daemon threads. (And even when exiting, I don't recall any mention of "immediately")
