I developed my custom jira plugin for jira 7.1.6 version via atlassian plugin sdk version 6.3.4.
And it works for a long time.
Now, I have to upgrade my Jira Software version 7.1.6 to 7.11.2.
So, I'm checking plugin compatibility between 7.1.6 and 7.11.2.
I upgrade my jira to 7.11.2 and install my custom plugin, but it doesn't work.
In atlassian-jira.log file, there are just two lines and not much informations.

I think plugin doesn't loaded normally.
What is the problem?
