初学java mina架构，先收到messageReceived事件 后收到sessionOpened事件 下面贴出了输出日志

[17:51:34] DEBUG - Event MESSAGE_RECEIVED has been fired for session 6
[17:51:34] INFO - CREATED
[17:51:34] INFO - OPENED
[17:51:34] DEBUG - Firing a SESSION_OPENED event for session 7
[17:51:34] INFO - RECEIVED: HeapBuffer[pos=0 lim=490 cap=2048: 47 45 54 20 2F 20 48 54 54 50 2F 31 2E 31 0D 0A...]
[17:51:34] DEBUG - Firing a MESSAGE_RECEIVED event for session 7
[error] getId():7 , not call sessionOpened
create mina io session getId():7
[17:51:34] DEBUG - Event MESSAGE_RECEIVED has been fired for session 7

已解决，两个函数分别在不同的线程里。

日志的输出，不能100%判断先后 。。。。。。。。

你说呢...
