### Question:
SslTransportLayer implements TransportLayer { protected void startHandshake() throws IOException { this.netReadBuffer = ByteBuffer.allocate(netReadBufferSize()); this.netWriteBuffer = ByteBuffer.allocate(netWriteBufferSize()); this.appReadBuffer = ByteBuffer.allocate(applicationBufferSize()); netWriteBuffer.position(0); netWriteBuffer.limit(0); netReadBuffer.position(0); netReadBuffer.limit(0); handshakeComplete = false; closing = false; sslEngine.beginHandshake(); handshakeStatus = sslEngine.getHandshakeStatus(); } SslTransportLayer(String channelId, SelectionKey key, SSLEngine sslEngine, boolean enableRenegotiation); static SslTransportLayer create(String channelId, SelectionKey key, SSLEngine sslEngine); @Override boolean ready(); @Override boolean finishConnect(); @Override void disconnect(); @Override SocketChannel socketChannel(); @Override boolean isOpen(); @Override boolean isConnected(); @Override void close(); @Override boolean hasPendingWrites(); @Override void handshake(); @Override int read(ByteBuffer dst); @Override long read(ByteBuffer[] dsts); @Override long read(ByteBuffer[] dsts, int offset, int length); @Override int write(ByteBuffer src); @Override long write(ByteBuffer[] srcs, int offset, int length); @Override long write(ByteBuffer[] srcs); Principal peerPrincipal(); SSLSession sslSession(); @Override void addInterestOps(int ops); @Override void removeInterestOps(int ops); @Override boolean isMute(); @Override long transferFrom(FileChannel fileChannel, long position, long count);  }### Answer:
@Test public void testClientEndpointNotValidated() throws Exception { String node = "0"; clientCertStores = new CertStores(false, "non-existent.com"); serverCertStores = new CertStores(true, "localhost"); sslServerConfigs = serverCertStores.getTrustingConfig(clientCertStores); sslClientConfigs = clientCertStores.getTrustingConfig(serverCertStores); SslChannelBuilder serverChannelBuilder = new SslChannelBuilder(Mode.SERVER) { @Override protected SslTransportLayer buildTransportLayer(SslFactory sslFactory, String id, SelectionKey key, String host) throws IOException { SocketChannel socketChannel = (SocketChannel) key.channel(); SSLEngine sslEngine = sslFactory.createSslEngine(host, socketChannel.socket().getPort()); SSLParameters sslParams = sslEngine.getSSLParameters(); sslParams.setEndpointIdentificationAlgorithm("HTTPS"); sslEngine.setSSLParameters(sslParams); TestSslTransportLayer transportLayer = new TestSslTransportLayer(id, key, sslEngine, BUFFER_SIZE, BUFFER_SIZE, BUFFER_SIZE); transportLayer.startHandshake(); return transportLayer; } }; serverChannelBuilder.configure(sslServerConfigs); server = new NioEchoServer(ListenerName.forSecurityProtocol(SecurityProtocol.SSL), SecurityProtocol.SSL, new TestSecurityConfig(sslServerConfigs), "localhost", serverChannelBuilder); server.start(); createSelector(sslClientConfigs); InetSocketAddress addr = new InetSocketAddress("localhost", server.port()); selector.connect(node, addr, BUFFER_SIZE, BUFFER_SIZE); NetworkTestUtils.checkClientConnection(selector, node, 100, 10); }
