DownstreamPassCondition.jobs is in some places (e.g. getJobList) interpreted as a list of paths relative to the current job, yet in other places as a list of absolute paths (e.g. contains). Also there is no form validation on this field. The result is that you may be tempted to use a relative path to a downstream job in the same folder, but the promotion will silently never occur unless you use an absolute path.
