-------------------------------------

             Summary: Weak reference targets added after the reference property are not indexed
                 Key: OAK-1242
                 URL: https://issues.apache.org/jira/browse/OAK-1242
             Project: Jackrabbit Oak
          Issue Type: Bug
    Affects Versions: 0.12
            Reporter: Tobias Bocanegra
            Priority: Blocker
             Fix For: 0.13


with the introduction of a special index for (weak)references by OAK-1137, they are only indexed if a reference property is written, but not if a weak reference target is added later on.

see {{org.apache.jackrabbit.oak.jcr.ReferencesTest#testWeakReferencesAddLater}} that fails currently.

the only workaround is to re-set the weak reference property after adding the referenceable node. 

looking at this regression, I don't think that the current approach of storing the back references is a good one as it does not work for this case. IMO a separate index of all reference properties, grouped by UUID of the target referenceable needs to be kept outside of the normal tree.
