项目使用JDK1.6真的很多崩溃的事情。
静待明年升级JDK1.8
JDK1.6解决方案一（无奈本地亲测无效T_____T）
https://blog.csdn.net/nk_tf/article/details/52175689
查看本SSL证书公钥长度：2048
可能问题根源之一：jdk1.6只支持1024字节的DH，我发现我证书的公钥是2048字节的，所以报错了，jdk1.7以上支持，所以成功。
SSL连接确认jdk1.8编译可以连接，但jdk1.6编译后无法连接

The "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files" answer did not work for me but The BouncyCastle's JCE provider suggestion did.
Here are the steps I took using Java 1.6.0_65-b14-462 on Mac OSC 10.7.5
1) Download these jars:
2) move these jars to $JAVA_HOME/lib/ext
3) edit $JAVA_HOME/lib/security/java.security as follows: security.provider.1=org.bouncycastle.jce.provider.BouncyCastleProvider
方法二（终极解决问题 ^______^）：
问题根域：需要手动加证书
