The following simple program, successfully serves up an ftp site. If

shows that the acceptor thread has started. The first one still works, as
expected. The second just sits there forever.
What OS is this on? I just ran the code on OS X and the second process
outputs the following and then exits:
In my case it was on Windows Vista x64, running a recent 32bit java 1.6.
Linux also responds "correctly". :)
Out of curiosity, I made the following little test program. It seems to
demonstrate the difference in behaviour on Windows and Linux.
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.InetAddress;
import java.net.InetSocketAddress;
import java.net.ServerSocket;
import java.net.UnknownHostException;
public class Reuse {
private static void bind() throws UnknownHostException, IOException {
Thread th = new Thread(new Runnable() {
@Override
public void run() {
try {
ServerSocket s = new ServerSocket();
s.setReuseAddress(true);
s.bind(new
InetSocketAddress(InetAddress.getLocalHost(), 12347));
s.accept();
} catch (Exception ex) {
ex.printStackTrace();
}
}
});
th.setDaemon(true);
th.start();
}
public static void main(String[] args) throws Exception {
bind();
Thread.sleep(1000);
bind();
System.out.println("bound. Press Enter.");
new BufferedReader(new InputStreamReader(System.in)).readLine();
}
}
