Confluence has been updated to version 6.15.9

Problem

Exalate reports an error that it has no permissions to comment on the issues.

Cause

The problem occurs whenever a Jira administrator sets a  jira.permission.comment.group Workflow property to prevent users from commenting on the issues with a certain status. 

Solution

Remove the Workflow property and communicate to all the users that they should not be commenting on the issues with the certain status.
