升级到2.7.4.1，这个bug已经修复了，cc之前没有判断
if(cc.getParameters() == null) {
cc.setParameters(new HashMap());
}
现在已经做了判断了

I have a doubt. I have reviewed the code and github commit log.


These two commit are next to each other.but I do not find the code had being move.Can you tell me why? @chickenlj

Closing this issue since fixed in 2.7.4.1

by the way @canglang1973, your question is not related to this issue right?
For my personal view, those two commits are not next to each other, there are in different branch until one merge into master branch

Oh ,Thanks your answer.
