I'm writing a game server using Java non-blocking SocketChannel. Sometimes I want to send a reply message and then close the channel, like the code below.

However, the close() method interrupts the write() method, I get a java.nio.channels.ClosedChannelException and the message is not sent.

I can pop a thread and wait for 1-2 seconds before closing the channel, but I feel it's so wasteful to making another thread.

What is the proper way to close a SocketChannel while there are pending operations?


String msg = "Wrong password!";
