标题[问题] java 1.6 vs 1.8 ssl socket连线问题
时间Thu Mar 26 11:34:25 2015
各位好，我想请教一个java 1.6 vs 1.8的问题
我目前有一支程式要跟主机用SSL沟通，丢一些资料
底下是我连线，收送的部分
我在jre1.6环境下跑
不用disconnect，只要socket建通，直接write and read
不管送收几次都可以
但是只要环境切到1.8下,第一次执行收送是成功的，
但只要在马上执行一次同样动作
主机那边似乎就收到他们解码不出来的东西，所以没有回应我
我client就会timeout
我疑惑的是
"socket建立起来，第一次收送，成功正常，但socket没有断，只是再第二次送资料，结
果就是主机收到解不出来的东西"
不知道有没有人可以给我一点方向去查问题呢
感谢回答

1F：推 reon: 我没用过1.8 但是Server端在收封包的时候 最好指定array大小 04/24 23:44
