自从昨天起，我无法从 JBoss EAP 6.2 连接到我的本地开发机上的 MicroSoft SQLServer (v11.1.3000.0)。现在 SQLServer 要通过 SSL 进行连接。
我收到以下异常信息：

当我连接到我们测试环境上的SQLServer(11.0.2100.60)时一切正常。
我已经完成了以下操作： - 确保我在Java 6 JRE中有正确的JCE库 - 更新了sqljdbc4.jar - 阅读：Java: Why does SSL handshake give 'Could not generate DH keypair' exception? 我还没有尝试上面文章中的解决方法。我更想停止SQLServer要求SSL。
如何停止SQLServer要求SSL连接？或者修复我的配置？这是怎么回事？SQLServer是否进行了自动更新？
