[undertow-dev] How to interrupt WebSocketClient.connect(...)

Is there way to cancel an outstanding WebSocketContainer.connectToServer(...) request ? A connection attempt to an offline server blocks a very long time (minutes), and debugging would indicate IoFuture<WebSocketChannel> seems unwilling to respect an interrupt/cancel from the main thread. IoFuture<WebSocketChannel> session = WebSocketClient.connect(xnioWorker, ssl, bufferPool, OptionMap.EMPTY, path, WebSocketVersion.V13, clientNegotiation); //TODO: fix this WebSocketChannel channel = session.get();
