NIO ServerSocketChannel Accepts in Mac OSX

Question

I've got a problem with using NIO in MacOSX. I used it in Linux/Windows and everything was fine. But now, when I try to start it in MacOSX, my program refuses to accept connections. Corresponding code:
        _selector = Selector.open();
        _serverSocketChannel = ServerSocketChannel.open();
        _serverSocketChannel.configureBlocking(false);
        _serverSocketChannel.register(_selector, SelectionKey.OP_ACCEPT);
        _serverSocketChannel.socket().bind(new InetSocketAddress(InetAddress.getByName(aHost), aPort));And place, where everything stops:
        while (true) {
            try {
                int selectedKeys = _selector.select();
...It does not matter, what goes next, because program stops here. I try to connect, through telnet/test program/etc.
All firewalls are turned off. Servers (apache/php) work fine here.
Please, help. I'm new with MacOSX, and do not know even what can be here.

Answer 1

I've found an answer, but I'm really confused with it. In MacOSX I needed to swap lines
        _serverSocketChannel.register(_selector, SelectionKey.OP_ACCEPT);
        _serverSocketChannel.socket().bind(new InetSocketAddress(InetAddress.getByName(aHost), aPort));to get it working. As I remember, reverse variant is recommended.
So, do I've to create two different variants for different OSes?
