[xSocket-develop] XSocket not closing underlying OS socket when close() is called

[Erin D. <eri...@gm...>]

Hi,

I am developing an application using xSocket. During the testing, it
gets shut down and started up again almost instantly. This makes it
crash with a "BindException: Address already in use".

It appears as though xSocket does not tell the operating system that
it has finished with the socket when close() is called. If I wait a
few minutes, the operating system realises the socket isnt being used
anymore and closes it, which means I can start my application again
without it throwing an error.

Is there a solution to this? Here is a test case displaying the behaviour:

import org.junit.Test;
import org.xsocket.connection.IHandler;
import org.xsocket.connection.Server;

/**
 * Tests rapid creation and destroying of xSocket sockets
 * Will throw an exception on the 2nd or 3rd iteration
 */
public class XSocketTest implements IHandler {

    @Test
    public void test() throws Exception {
        Server s;
        for (int x = 0; x < 500; x++) {
            s = new Server("localhost", 6789, this);
            s.start();
            Thread.sleep(100); //give it some time to initialise
            s.close();
        }
    }

}

I am using Linux 2.6 (in case this is NIO-related)

Cheers,
Erin
