      Description

      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).
