IBM MQ 在 SSL 握手时抛出 java.lang.UnsupportedOperationException

Question

打电话时：

MQQueueConnectionFactory cf ...
cf.createConnection();

com.ibm.mq.jmqi.remote.impl.RemoteTCPConnection.handshakeCompleted 方法开始：

public void handshakeCompleted(HandshakeCompletedEvent event) {
 X509Certificate[] peerCertificateChain = event.getPeerCertificateChain();
 ...

javax.net.ssl.SSLSession 中的 getPeerCertificateChain：

default X509Certificate[] getPeerCertificateChain() throws SSLPeerUnverifiedException {
    throw new UnsupportedOperationException("This method is deprecated and marked for removal. Use the getPeerCertificates() method instead.");
}

导致此异常：

Exception in thread "HandshakeCompletedNotify-Thread" java.lang.UnsupportedOperationException: This method is deprecated and marked for removal. Use the getPeerCertificates() method instead.
    at java.base/javax.net.ssl.SSLSession.getPeerCertificateChain(SSLSession.java:295)
    at java.base/javax.net.ssl.HandshakeCompletedEvent.getPeerCertificateChain(HandshakeCompletedEvent.java:173)
    at com.ibm.mq.jmqi.remote.impl.RemoteTCPConnection.handshakeCompleted(RemoteTCPConnection.java:2448)
    at java.base/sun.security.ssl.TransportContext$NotifyHandshake$1.run(TransportContext.java:685)
    at java.base/sun.security.ssl.TransportContext$NotifyHandshake$1.run(TransportContext.java:682)

    at java.base/sun.security.ssl.TransportContext$NotifyHandshake.run(TransportContext.java:682)
    at java.base/java.lang.Thread.run(Thread.java:832)

该项目唯一的 IBM MQ 依赖项是：

com.ibm.mq:com.ibm.mq.allclient:9.2.0.0

为什么 javax.net.ssl.getPeerCertificateChain() 调用该已弃用的方法？看起来问题出在 HandshakeCompletedEvent 类中，而不是 MQ 中。

编辑：此问题从 Java 15 开始。

Answer 1

在最新版本中，他们显然提供了 JAVA 17 支持。
