我使用的是Java服务器来验证苹果缴费收据与他们validation server。大约50％的请求失败，出现“SocketException：connection reset”，有效收据（稍后再次尝试成功）。重置连接（Java 8）
我没有遇到与部署在Java 7的另一台服务器这种行为，但启动时部署到Java 8
我看到默认的TLS协议在Java中8改为从使用TLSv1来的TLSv1遇到此。 2，所以我试图将默认协议更改为使用Java 7的默认协议，但没有看到任何改进。这是JVM属性我用：
-Djdk.tls.client.protocols="TLSv1,TLSv1.2,TLSv1.1"
任何想法，为什么我得到错误“SocketException：连接重置”大约一半的时间？
谢谢！

我设法调试和SSL日志失败的请求：SSL连接被成功抢通和验证发生
