Currently, we're able to trigger builds base on comments on Jira issues. However, the moment we try to use JQL to limit which issues will trigger a build (i.e., allow a build-message within issue "THJ2-1" to trigger a build but not the same build-message if commented within issue "THJ2-2") the job no longer triggers at all.

Nearly certain this is a user (me) error rather than a bug, but I've run out of useful Google search results. Any help in proper syntax/usage for the JQL box would be greatly appreciated.
