>
> A problem with loading recursively referenced entities was found when there
> is a complex relation of the following kind:
> Leaf <-> BranchConnection <-> Branch(1) <- Branch(2) <- ...
> where Branch has a self reference to itself.
> Using a FetchPlan with a fetch group that has a fetch attribute with
> recursionDepth=-1 does not produce the expected result and only the first of
> the Branch nodes is loaded.
> Loading a Leaf with 5 branches in a row and traversing through them fails
> right on level 3 (starting from 5 downwards) which leads to the thought that
> OpenJPA loads only the first element (along with its direct parent).
