You will find code samples for most of the AsynchronousCloseException methods.
Summary
Checked exception received by a thread when another thread closes the channel or the part of the channel upon which it is blocked in an I/O operation.
try (final var executor = Executors.newSingleThreadExecutor()) {
final var future = executor.submit(() -> {
try (final var channel = ServerSocketChannel.open()) {
System.out.println("bind ...");
channel.bind(new InetSocketAddress("127.0.0.1", 8000));
System.out.println("bind OK!");
System.out.println("accept ...");
channel.accept();
System.out.println("accept OK!");
} catch (AsynchronousCloseException e) {
System.out.println("AsynchronousCloseException!");
} catch (IOException e) {
System.out.println("IOException!");
}
});
TimeUnit.SECONDS.sleep(2);
System.out.println("-- future.cancel --");
future.cancel(true);
}
// Result
// ↓
//bind ...
//bind OK!
//accept ...
//-- future.cancel --
//AsynchronousCloseException!
