java为什么SSL握手有时会杀死我的CPU？
我们遇到了一个非常奇怪的问题：我们正在使用修改后的SeleniumHTTP代理（更类似于BrowserMob Proxy），发现在某些情况下（我们无法可靠地重现），CPU在处理SSL连接时会停止运行
堆栈转储显示线程在此处被卡住：

多个堆栈转储显示generateSafePrimes（）在持续运行，每个后续堆栈转储在java中显示的位置略有不同。数学正在运行的BigInteger。然而，很难说事情到底在哪里被卡住了，或者是否存在合法的无限循环（尽管我对此表示怀疑）
通过进一步调查，我能够使用-Djavax捕获相关输出。网debug=ssl集，用于工作示例和中断示例
当一切正常时，握手几乎立即发生，我们看到了这个调试输出，从而产生了一个适当的Diffie-Hellman密钥交换：

该日志跨越了2分钟的时间范围，在这段时间内几乎什么都没有发生。还有一些与sb SSL相关的附加SSL日志记录。谷歌。com（它也会阻止），但这可以忽略-它只是Firefox浏览器签入到Google's safe browsing API
我应该注意到：大约一个月前，Selenium代理也受到了类似的complaints指控，但升级到BouncyCastle的最新版本后，这些指控被resolved。然而，我们发现问题仍然偶尔发生，我们无法找出原因
我希望StackOverflow家族能够解释为什么有时候线程会卡在组织中。弹跳船舱。加密。发电机。卫生防护架。生成安全素数，其他时候，日志显示我们立即直接进入这一关键行：
%% Created: [Session-10, TLS_DHE_RSA_WITH_AES_128_CBC_SHA]
谢谢你的洞察力
编辑：我应该补充一点，我们在Linux上使用Java 1.6.0_18-b07（32位和64位受影响）、Selenium 2.21和BouncyCastle 1.47
编辑#2：我刚刚确认使用Java7时不存在这个问题
# 1 楼答案
因此，请检查完整的注释线程，但基本上经过大量调试后，我发现升级到Java7解决了这个问题。不确定Java6最初的问题是什么，但我们将继续讨论Java7。我希望这对将来的人有帮助
