证书未偶尔发送

Question

在我的应用程序中，我有 2 个组件与 REST（基于客户端-服务器）相互通信。
可以将应用程序配置为使用 HTTP 或 HTTPS（自签名证书）。

有时，当我在 HTTPS 模式下启动应用程序时，我的客户端无法与服务器通信。我收到以下异常：

    09-16-2013 12:28:52 [dispatcher] [http-nio-8143-exec-8] [INFO] - Exception while dispatching request
java.util.concurrent.ExecutionException: com.sun.jersey.api.client.ClientHandlerException: javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
    ...
Caused by: com.sun.jersey.api.client.ClientHandlerException: javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
    ...
Caused by: javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
    ...
Caused by: java.io.EOFException: SSL peer shut down incorrectly
    ...

当我停止并启动应用程序时，一切都按预期工作。
我尝试寻找解决方案，但找不到与我的问题相似的任何内容，因为不时发生并通过重新启动修复，所有问题都是一致的。

Java

版本： Oracle Corporation， 'Java HotSpot（TM） 64-Bit Server VM'， 1.7.0_17-b02操作系统：红帽知道吗？

更新
事实证明，这也可能在应用程序工作一段时间后发生。意思是，一切正常，SSL通信正常，突然发生此错误，直到我重新启动客户端才会解决。

我能够重现 -Djavax.net.debug=all 的问题，显然证书不是从客户端发送的，问题是为什么。由于有时一切顺利，什么会导致事情不时出错？

Answer 1

javax.net.ssl.SSLHandshakeException: null cert chain

看起来服务器需要客户端证书，而您没有发送或发送无效的内容。客户端 SSL 日志中将有一个入站CertificateRequest，该后不跟出站Certificate消息，或者后跟空消息。

Answer 2

显然有人添加了覆盖证书的代码：

        HttpsURLConnection.setDefaultSSLSocketFactory(ctx.getSocketFactory());

我删除了这一行，现在一切正常。
