> The loop detection code in Threader.buildContainer() is currently:
>                 // Link references together in the order they appear in the References: header,
>                 // IF they dont have a have a parent already &&
>                 // IF it will not cause a circular reference
>                 if ((parentRef != null)
>                     && (ref.parent == null)
>                     && (parentRef != ref)
>                     && !(parentRef.findChild(ref))) {
>                     // Link ref into the parent's child list
> Deep circular references where 'parentRef' is already a child of 'ref' and ref is the root container are possible.
> The test should be:
>                if ((parentRef != null)
>                     && (ref.parent == null)
>                     && (parentRef != ref)
>                     && !(ref.findChild(parentRef))) {
>                     // Link ref into the parent's child list
