JIRA Plugin shouldn't using contains to compare JIRA ID,it will match other JIRA ID and the comment will become more and more confused.
example:
I have 4 change list and 4 JIRA issue,each change list description like below.
ChangeList:Description
1:JIRA-1
2:JIRA-11
3:JIRA-12
4:JIRA-13

when i build the project,there are four changelist description will be in the JIRA-1 issue comment.

I just find the code, maybe it is because using contains to compare JIRA ID.
