We would like to be able to mark an issue open to certain people who would otherwise not have access to it, either through project or issue priority schemes.

What we initially thought we could do was to mark the users as watchers of a particular issue, which would then allow the user to get emails when the issue changes. While this works (apparently due to bug JRA-5743), it doesn't allow the user additional access to the issue over time through the web interface. What we would like is an additional option on the Issue Security Scheme to support allowing anyone marked as a watcher of an issue to be able to be in a security level.

The particular use case is:

• User submits a "help desk" request. This goes to the "Help Desk" project
• The Help Desk project has a "Reporters and Developers" issue security system
• Developer realizes that this requires development (rather than just a quick fix) and is already being tracked by an issue in the "Core" project
• Developer marks the "Help Desk" issue as a duplicate of the "Core" issue and makes the original reporter of the "Help Desk" issue a watcher on the "Core" issue
• From here, while the reporter would otherwise not be able to see anything in the "Core" project, because a developer has made him watch that issue, he should be able to see it.

This was originally tracked in the Atlassian support system as JSP-864.
