> the access 'itemCache' map in ItemManager is mostly synchronized by not via the ItemStateListener
methods:
> [...]
>     public void stateCreated(ItemState created) {
>         ItemImpl item = retrieveItem(created.getId());
>         if (item != null) {
>             item.stateCreated(created);
>         }
>     }
> [...]
>     private ItemImpl retrieveItem(ItemId id) {
>         return (ItemImpl) itemCache.get(id);
>     }
> [...]
> this can result in a corruption of a map (eg subsequent accesses may result in a endless
loop).
