Thread join(milliseconds) not killing thread in Java

I am trying to timeout a running Thread with a Thread.join(millis), but it just hangs and does not timeout. What could be the cause of this? Sample code

public static void main(String[] args) throws InterruptedException {
    final Thread t1 = new Thread(() -> {
        for (int i = 0; i < 100000000000000000L; i++) {
        }
    });
    t1.start();
    t1.join(100);
    System.out.println("t1.join called");
}

It's not meant to kill the thread. It is meant to wait for it to exit up to the timeout value, and then to throw InterruptedException to the current thread if the timeout expired. See the Javadoc.
