Emmanuel Lecharny resolved DIRMINA-804.
---------------------------------------
Resolution: Cannot Reproduce
In 2.0.7, the datagram is closed as soon as the unbind is done (I did the
test). The pb should have been fixed a while ago, or this is a typical Windows
7 issue.
> NioDatagramAcceptor.unbind does not unbind cleanly
> --------------------------------------------------
>
> Key: DIRMINA-804
> URL: https://issues.apache.org/jira/browse/DIRMINA-804
> Project: MINA
> Issue Type: Bug
> Components: Transport
> Affects Versions: 2.0.0
> Environment: Windows 7
> Reporter: Zhou
> Fix For: 2.0.8
>
>
> Steps to reproduce:
> 1. Use below code.
> {code}
> NioDatagramAcceptor acceptor = new NioDatagramAcceptor();
> acceptor.setHandler(new IoHandlerAdapter());
> SocketAddress localAddress = new InetSocketAddress("localhost",9001);
> acceptor.bind(localAddress);
> acceptor.unbind(localAddress);
> {code}
> 2. use debugger to step over here after unbind() call but before exiting the
> process
> 3. use netstat to check current UDP sockets. you can find port 9001 not
> released yet.
> Possible solution: invoke selector.selectNow() after closing the channel.
> {code}
> @Override
> protected void close(DatagramChannel handle) throws Exception {
> SelectionKey key = handle.keyFor(selector);
> if (key != null) {
> key.cancel();
> }
>
> handle.disconnect();
> handle.close();
> selector.selectNow();
> }
> {code}
