HttpClientBuilder问题：无法初始化类sun.security.ssl.SSLContextImpl $ CustomizedTLSContext

Question

在下面的Java代码中，我随机收到以下错误。

 final HttpClient client = HttpClientBuilder.create().build();
         final HttpGet request = new HttpGet(requestParameters);
         final HttpResponse response = client.execute(request);

错误：

java.lang.NoClassDefFoundError: Could not initialize class sun.security.ssl.SSLContextImpl$CustomizedTLSContext
    at java.base/java.lang.Class.forName0(Native Method)
    at java.base/java.lang.Class.forName(Class.java:291)
    at java.base/java.security.Provider$Service.getImplClass(Provider.java:1848)
    at java.base/java.security.Provider$Service.newInstance(Provider.java:1824)

    at java.base/sun.security.jca.GetInstance.getInstance(GetInstance.java:164)
    at java.base/javax.net.ssl.SSLContext.getInstance(SSLContext.java:168)
    at org.apache.http.ssl.SSLContexts.createDefault(SSLContexts.java:51)
    at org.apache.http.impl.client.HttpClientBuilder.build(HttpClientBuilder.java:977)

我无法重现该问题，因为它是随机的。这是否意味着ssl / tls握手失败？

实施重试政策是否可以帮助纠正此问题？

  public DefaultHttpRequestRetryHandler() {
        this(3, false);
    }

以下是我正在使用的Java库：

更新：虽然我认为我可以通过从HttpClientBuilder转到java.net.HttpUrlConnection摆脱这个问题，但不幸的是，我遇到了同样的错误：

我的Java版本是1.8.0_171。通过升级到1.8.0_261，解决了相同的问题。
