Java 1.7 にアップグレードした後、「unrecognized_name」という SSL ハンドシェイク アラートが表示されるのはなぜですか?

-Djsse.enableSNIExtension=false

System.setProperty("jsse.enableSNIExtension", "false");

// Create an SSLSocket with the desired hostname
SSLSocket sslsock = ...

// Attempt handshake
try {
    // This will block until the attempt succeeds or fails.
    sslsock.startHandshake();
} catch (SSLException e) {
    // Handle the exception here. If it contains the "unrecognized_name" message, disable SNI and retry.
}

// Disable SNI and retry handshake without hostname
if (e.getMessage().contains("unrecognized_name")) {
    sslsock = ... // Create an SSLSocket without specifying a hostname
    sslsock.startHandshake();
}

// Custom trust management (for untrusted certificates)
TrustManager[] trustAllCerts = ...

// Built-in trust manager
TrustManager[] trustManagers = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm()).getTrustManagers();
