我正在用tls/ssl函数编写一个socketserver库，但我的代码中有一个问题。
如果我加载密钥库文件，它会抛出一个ioexception，但证书会在浏览器中完全显示。
我的代码：

SSLServerSocketFactory factoryIO;
FileManager certificateIO = new FileManager(CacheHandler.fileIO.getPath("database") + "letsencrypt.jks");
char[] passphraseIO = "12345678".toCharArray();

if (certificateIO.exits()) {
    //this.socketIO = SSLServerSocketFactory.getDefault().createServerSocket(this.networkIO.getPort(), 10, this.networkIO.getAddress());
    //this.socketIO = this.getContext().getServerSocketFactory().createServerSocket(this.networkIO.getPort(), 10, this.networkIO.getAddress());

    // Load Key Store.
    KeyStore storeIO = KeyStore.getInstance("JKS");
    storeIO.load(certificateIO.stream(), passphraseIO);

    // Initialize Key Manger.
    KeyManagerFactory managerIO = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
    managerIO.init(storeIO, passphraseIO);

    // Initialize Trust Manger.
    // TrustManagerFactory trustIO = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
    //trustIO.init(storeIO);

    // Initialize SSL Context with Trust and Key Manager.
    SSLContext contextIO = SSLContext.getInstance(this.protocolIO);
    contextIO.init(managerIO.getKeyManagers(), null /*trustIO.getTrustManagers()*/, null);

    factoryIO = contextIO.getServerSocketFactory();
    // ((SSLServerSocket) this.socketIO).setWantClientAuth(true);
    //((SSLServerSocket) this.socketIO).setEnabledCipherSuites(new String[]{"TLS_DHE_DSS_WITH_AES_256_CBC_SHA256"});
    //((SSLServerSocket) this.socketIO).setEnabledProtocols(new String[]{"TLSv1.2"});

我尝试了很多方法，但我无法让它在没有这个错误的情况下运行，我尝试了一段时间，但我不知道是什么导致了这个错误。
这将引发以下异常：

我通过以下命令生成密钥库文件：

keytool -genkeypair -keyalg RSA -alias selfsigned -keystore keystore.jks -storepass 12345678 -dname "CN=localhost, OU=Developers, O=Bull Bytes, L=Linz, C=AT"
