>             Project: Jackrabbit Content Repository
>          Issue Type: Bug
>          Components: jackrabbit-core
>    Affects Versions: 1.6.1
>            Reporter: Cédric Damioli
>            Priority: Critical
>             Fix For: 1.6.3

> I've written the following snippet to illustrate the issue :
>         Node root = session.getRootNode();
>         
>         Node a = root.addNode("a");
>         Node b = root.addNode("b");
>         b.addMixin("mix:referenceable");
>         
>         a.setProperty("p", b);
>         
>         root.save();
>         
>         System.out.println(b.getReferences().getSize());     // --> correctly returns 1
>         
>         a.setProperty("p", (Node) null);
>         a.setProperty("p", b);
>         
>         root.save();
>         
>         System.out.println(b.getReferences().getSize());    // --> returns 0 !
> When the ChangeLog is processed, added references are processed before deleted ones, so the persisted NodeReferences is finally wrong.
> I've set the priority of this issue to critical, because the persisted references count is corrupted.
> A simple workaround is to first remove the property, then save, then add the property again, but it not satisfying.
