我面临标准 java http 客户端的问题。由于某种原因，我还不知道它会进入无限循环并利用我拥有的所有CPU。下面是示例堆栈跟踪和无限循环运行的方法。

我认为问题的根本原因是this https://stackoverflow.com/questions/54485755/java-11-httpclient-leads-to-endless-ssl-loop一。但禁用 TLSv1.3 后问题并没有消失。
我在应用程序启动时使用调试检查了 TLSv1.3 是否以以下方式禁用：
这是我传入的 JVM 参数：
-Djdk.tls.disabledAlgorithms="TLSv1.3"
-Dhttps.protocols="TLSv1,TLSv1.1,TLSv1.2"
-Djdk.tls.client.protocols="TLSv1,TLSv1.1,TLSv1.2"
-Djdk.tls.server.protocols="TLSv1,TLSv1.1,TLSv1.2"
确保 TLSv1.3 已禁用。
请问，您知道问题的原因是什么吗？
