sync.wait();

In most RMI server code examples there are these lines of codes at the end of the server constructor. What is the purpose of them.
Even without them a server works perfectly.

// wait for invocations from clients
Object sync = new Object();
synchronized (sync) {
sync.wait();
}

Kind regards
Charles.

The only thing I can think of is that it's there to keep a non-daemon thread alive. If the main() thread would simply exit, the entire JVM would exit because the threads used internally by RMI are all daemon threads.
