Hello,
After upgrading to JIRA 6.2 I tried to use developer panel. I see that there was commit but after I click on the link, windows appear with message "You don't have access to view all related commits. Please contact your administrator.". I'm administrator on both Fisheye and JIRA so permission shouldn't be the problem. I see in Source tab what commits without any problem. I tried viewing log but I didn't see any logs about problems with permissions.
