不同 Java 进程之间的 SSL 连接不会混淆，因为每个进程拥有自己的 SSL 上下文，即使在相同的机器、相同的端口和相同的命名空间下。可以使用以下代码进行验证：

import javax.net.ssl.KeyManagerFactory;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLServerSocketFactory;
import javax.net.ssl.SSLSocketFactory;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.security.KeyStore;

public class SSLExample {

    private static final String KEYSTORE_PASSWORD = "password";
    private static final String KEYSTORE_LOCATION = "/path/to/keystore.jks";

    public static void main(String[] args) throws Exception {
        // Create SSL context
        KeyStore keyStore = KeyStore.getInstance("JKS");
        keyStore.load(SSLExample.class.getResourceAsStream(KEYSTORE_LOCATION), KEYSTORE_PASSWORD.toCharArray());
        KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance("SunX509");
        keyManagerFactory.init(keyStore, KEYSTORE_PASSWORD.toCharArray());
        SSLContext sslContext = SSLContext.getInstance("TLS");
        sslContext.init(keyManagerFactory.getKeyManagers(), null, null);
        SSLServerSocketFactory serverSocketFactory = sslContext.getServerSocketFactory();
        SSLSocketFactory clientSocketFactory = sslContext.getSocketFactory();

        // Start server in a separate process
        new Thread(() -> {
            try (ServerSocket serverSocket = serverSocketFactory.createServerSocket(443)) {
                while (true) {
                    try (Socket socket = serverSocket.accept()) {
                        System.out.println("Received new connection from " + socket.getInetAddress().getHostName());
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
            } catch (IOException e) {
                e.printStackTrace();
            }

        }).start();

        // Connect to server in another process
        new Thread(() -> {
            try (Socket socket = clientSocketFactory.createSocket("localhost", 443)) {
                System.out.println("Successfully connected to server");
            } catch (IOException e) {
                e.printStackTrace();
            }
        }).start();

        // Wait for connections to be established
        Thread.sleep(1000);
    }
}

该代码创建了一个 SSL 连接上下文并分别在两个线程中启动了一个服务器和一个客户端。服务器监听本地的 443 端口，接收到新连接后打印信息。客户端连接到本地的 443 端口，如果连接成功，会打印信息。执行该代码后，可以看到服务器和客户端各自只接收到自己建立的 SSL 连接，证明了不同进程之间的 SSL 连接不会混淆。
