Have you looked at the API yet?

In plain english: "If the thread exists and it is running then lets busy wait until it terminates". Busy waiting is evil and its use is quite limited. This is not the right place for a busy wait, that piece of code has some room for improvement... It would probably be better to use this:

if (thrdUpdate != null) {
    thrdUpdate.join();
    thrdUpdate = null;
}
