我尝试使用javaMail v1.5.3连接到office365邮件服务器（应用程序部署在tomcat 6上）。我在启动时运行一个线程，它在一分钟睡眠的循环中检查新电子邮件。在大多数情况下，连接成功建立，一切正常，但有时我得到 “握手期间远程主机关闭连接”错误。
错误是由
引起的Caused by: java.io.EOFException: SSL peer shut down incorrectly
at sun.security.ssl.InputRecord.read(InputRecord.java:482)
at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:934)
我尝试过来自以下方面的问题： How to make Java 6, which fails SSL connection with "SSL peer shut down incorrectly", succeed like Java 7? 和javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake：
将-Dhttps.protocols=TLSv1,SSLv3和 - Dsun.security.ssl.allowUnsafeRenegotiation=true添加到我的tomcat环境中
但我没有得到任何结果。仍然 - 随机发生异常。
我在javax.net和IMAP连接上启用了调试模式并获得了结果：
当连接没有正确建立时，log看起来像这样：

然后去证书等
所以我很奇怪是什么导致这种不一致的行为。
