             Summary: DistributionPackageUtils#disposable should handle hanging packages
                 Key: SLING-6589
                 URL: https://issues.apache.org/jira/browse/SLING-6589
             Project: Sling
          Issue Type: Bug
          Components: Content Distribution
    Affects Versions: Content Distribution Core 0.2.0
            Reporter: Timothee Maret
            Assignee: Timothee Maret
             Fix For: Content Distribution Core 0.2.6


Before the fix SLING-6503, some package could have been left hanging without {{refs}} node, thus causing the async package collection to log

Those hanging packages can't be produce thanks to SLING-6503, but the existing ones must be handled. In order to be on the safe side, the packages should be considered as non-collectable.
